PXE Mission

PXE International

  • Initiates, funds, and conducts research;
  • Provides support for individuals and families affected by pseudoxanthoma elasticum; and
  • Provides resources for healthcare professionals.
PXE Funding

PXE International is a 501(c)(3) not-for-profit organization established in 1995. PXE International research began and continues its funding mostly through private donations. The seeds planted by these small donations have grown into grants from foundations, companies, and the government. The success of our activities and our mission depends on the generosity of you, our supporters. Our tax filings and annual reports are available here.

PXE History


Patrick and Sharon Terry founded PXE International in 1995 to accelerate research that will result in the treatment of pseudoxanthoma elasticum. PXE International initiates, funds, and conducts research; provides support to affected families; and supports physicians.


Initial Plan

Pat was a fire sprinkler designer and Sharon was a former college chaplain when they learned in 1994 that their children (Elizabeth, born 12/12/87, and Ian, born 7/12/89) had PXE. Although they had no formal scientific background, they read medical literature, met with scientists and within two months crafted a comprehensive research plan (Figure 1).

Figure 1 - PXE Research Plan

The principles of the design are:

  • Fast track all phases of research simultaneously in order to avoid bottlenecks
  • Position the foundation as a firewall between patients and researchers to ensure maximum research participation
  • Initiate, fund, conduct and coordinate research in a central role to maximize efficiency and speed
  • Participate in the national genetics arena to leverage resources otherwise unavailable
  • In all cases, effect change on a systems level so that all diseases benefit 




The Terrys established PXE International as a 501 (c) (3). They enlisted Dr. Lionel Bercovitch of Brown University as medical director. Dr. Bercovitch is trained in both dermatology and ophthalmology and is selflessly dedicated to long hours of volunteer work for the foundation. A dedicated board and staff provide expertise and assistance.  Except for projects supported by grants from Yardi, the Helmsley Foundation and a few small family foundations over the years, all activities are funded through private donations  Our research meetings have an excellent track record of being funded by NIH grants.

During the first few years, PXE International:

  • Assessed the state of PXE research, including a gap analysis and the funding of small projects in the gap as a way to gather enough data to apply for government and industry grants.
  • Planned a cohesive strategy to avoid overlap and encourage innovative collaborative methods.
  • Established a large registry (see Figure 2) to form the cohort needed for robust studies.
  • Founded the PXE International Registry and BioBank, whose samples now number in the thousands. This lay-managed and -owned bank was the first of its kind in the world and is the model on which the Genetic Alliance Registry and BioBank is founded.

Discovery of the Gene Associated with PXE

The PXE International Blood and Tissue Bank accelerated the discovery of the gene associated with PXE, and Patrick and Sharon Terry participated in the research. In addition to participating in actual wet bench work, they worked to coordinate the activities of a number of laboratories around the world. They were able to get two groups to cooperate, a rare event in the race to find a gene in the 1990's, and the two groups published articles in Nature Genetics. Sharon was a co-author of both articles. As a result of PXE International's material involvement in the discovery, Sharon Terry was listed as a co-inventor on the patent and then assigned her rights to PXE International. The patent issued in the United States in August 2004 and in Canada September 2009. It has been licensed to GeneDx for the diagnostic test.

Mutation Analysis

PXE International piloted a system to combine the standardization of mutation detection and the input of phenotypic information by placing three dHPLC machines in labs in Belgium and South Africa. Using state-of-the-art informatics, over 100 mutations were discovered and a basis was formed for the development of a diagnostic kit for PXE, which is now available from GeneDx. To date, over 400 mutations have been catalogued. More information on the mutation database



Diagnostic Kit

PXE International, as part of the federal Collaboration, Education and Test Translation (CETT) program, offers a genetic test for PXE through GeneDx. This is the first diagnostic test for PXE. PXE International has worked to make the test affordable, high quality, with broad access and appropriate genetic counseling. This test helps families understand if siblings of affected individuals have PXE, and may also allow therapies to be targeted to specific mutations determined by the test.

Cellular and Molecular Studies

PXE International is funding research in a number of labs studying cell structure and function. One such study includes cytochemical and immunocytochemical localizations, X-ray microanalysis, and confocal microscopy image analysis. This effort will be instrumental in characterizing subcellular organelle behaviors, cellular behavior, and tissue-specific phenotypes.

Another laboratory is conducting cellular protein assay experiments for functional understanding of recombinant protein using the baculovirus insect cell system. This research seeks to characterize the previously observed protein degradation, cellular response to accumulation of unfolded mutant integral membrane proteins in the endoplasmic reticulum, posttranslational modification, and purification of recombinant ABCC6/MRP6 proteins in cells using recombinant baculovirus transfer cell expression plasmids. The purpose of this work is protein purification, targeted peptide design, peptide purification, testing of customized monoclonal antibodies, protein expression characterization, enzymatic functional description, structural dynamic range, and primary functional analysis of wild type and mutant proteins.



PXE Research Meeting

PXE International coordinated and funded the 2012 PXE Research Meeting, held on September 24-25, 2012 at the Bethesda North Marriott Hotel and Conference Center in suburban DC. This was the fourth international research meeting sponsored by PXE International, and the first completely funded by PXE International. Previous research meetings took place in 1997, 2004 and 2010, supported by NIH grants.

The overall goal of the meeting was to provide a forum for investigators to discuss relevant advances in transporter biology, metabolism, genetics, animal models, biomarker investigations and epidemiology, and for clinically oriented colleagues and PXE International to jointly plan for future research and translational applications. Attendees represented a broad spectrum of individuals with varying expertise including practicing clinicians caring for patients with PXE, physician-scientists and basic science investigators and lay leaders, all of whom share an interest in PXE.

Clinical Trials

With support from the NIH, PXE International continues to plan a clinical trial to examine the effects of multiple treatments for the vision loss caused by PXE. This will take place at the National Institutes of Health (NIH).

During 2013-2014, Dr. Mark Lebwohl and his research team at Mt. Sinai School of Medicine's Dermatology Department in New York are conducting a two-year study of oral magnesium supplementation as an investigational treatment for PXE. The purpose of this study is to evaluate the effectiveness of magnesium oxide supplements on the reversal of calcium deposits in the skin, and the yellow bumps and folds of skin in subjects with pseudoxanthoma elasticum (PXE). Magnesium oxide is a dietary supplement that has been shown in some research to reduce these calcium deposits.




PXE International is in a unique and powerful position to advocate for individuals affected by PXE, and our work is vital to them and to others facing similar struggles. It is the only hope for many individuals who desperately fear blindness. PXE International is also a role model for many other groups throughout the world.

Despite the now millions of dollars we have placed into service towards PXE research via the NIH, much remains to be done. In the United States, the NIH funds basic research. While this research is critical, we need to move to the next step and look at translating research into treatments. We have a number of labs ready to work on this – it is not only up to us to garner the funds to move forward. It is essential, not only to those affected by PXE but also to other groups, to analyze the incredible gold mine of data we have gathered in our search to understand and meet the challenge of PXE. Working into the wee hours of the morning, our fatigue abates through a burning desire to prevent blindness and other difficulties for the thousands of people on our registry. And in so doing, we are creating a new model of partnership between practitioners, researchers and the individuals they serve.

Finding sparse, uncoordinated research on their children’s rare disease, a couple starts their own organization to jumpstart hopes for the future.

by Sharon F . Terry 

PREFACE: The promise that genetics holds for improving the diagnosis, prevention, and treatment of disease is staggering if not yet fully realized. Such hopes are based on the successful mapping of the human genome and discovery of the genes that mark us for particular maladies—developments that some- day could lead to cures for diseases such as cancer, Alzheimer’s, or diabetes. With this new knowledge and the technology to apply it, however, come questions about what we do with what we know. A host of moral, ethical, and legal uncertainties, at both the pol- icy and personal levels, surrounds the use of genetic technologies. After Sharon Terry dis- covered that her children had a rare genetic disease, she and her husband took a crash course in genetics, founding an organization whose aim is to accelerate research on their children’s condition. Her story reveals the power that proactive parents can wield in expediting research while protecting the privacy of affected families. For all of its potential to cure disease, however, genetic technology also equips us with painful knowledge. Writer Lisa Sweetingham tells us about a couple facing agonizing decisions because of what genetic testing could reveal about their unborn baby’s health.


In 1994 we didn’t know a gene from a hubcap. We thought we didn’t need to know. The brave new world of genetics was vaguely interesting but not part of our world—not until our children were diagnosed with a rare genetic condition and we were thrown headlong into a chasm. The chasm was really a threshold. We crossed it, abandoning our ignorance of medical research and clinical treatments for the other side—a desperate need for those systems to per- form exceptionally well. The leap across that threshold took seconds, but learning the realities of these systems was an arduous, eye-opening journey that led us to start a foundation and a new model for accelerating research.

Our children, Elizabeth and Ian, now ages fifteen and thirteen, have pseudoxanthoma elasticum (PXE), a rare genetic condition that causes vision loss, premature wrinkling, and cardiovascular and gastrointestinal disease. The condition’s worst complication is vision loss, devastating people with PXE when they are be- tween thirty and forty.

Two days before Christmas 1994, I brought Elizabeth, then age seven, to a dermatologist. She had small bumps on the sides of her neck that had not disappeared since I had first spotted them a year before. Our pediatrician didn’t think they warranted attention and assumed that my worry was spurred by the recent death of my brother from a brain tumor.

The dermatologist knew immediately that these bumps were a sign of PXE. Glancing at Ian, then five, he said, “Ah, he has it too.” He asked if he could biopsy Elizabeth’s neck and examine her eyes. Confused and terrified, I consented. Why would a dermatologist examine eyes for a skin condition? I learned all too quickly that many skin problems are part of larger, systemic conditions. I also learned that we were fortunate that the dermatologist we chose, who happened to be a neighbor, also happened to be an ophthalmologist. He could do a preliminary assessment of the disease’s effects on my children’s eyes.


Distrusting The System

I came home numb and terrified. I called Pat, my husband, desperately wishing he had come to the appointment with us. When you ask our children what they remember from that day and the following weeks, they reply, “The best Christmas ever! We got every toy we asked for!” We recall this period as a time of great fear and confusion as we delved into a morass of medical literature, trying to sort truth from fiction. Popular medical resources such as the Merck Manual described the condition in dire terms, including the possibility that our kids would die at age thirty. What most jarred us was the realization that the research-medical system was not a well-oiled machine. We began to understand

that we could not expect accurate information or a course of treatment.

The only light in the season was our dermatologist, Lionel Bercovitch, who lived a few houses away and knew of our shock and sadness. He suggested we talk about the diagnosis and offered to meet with us at a neighbor’s house, so that our children would not overhear our discussion. And so on Christmas Eve we learned about genes, recessive inheritance, pedigrees, and mutations. The doctor was frank about the limited understanding of the condition. A sense of foreboding began to overlay this already traumatic journey, which was starting to resonate with another experience—my brother’s death.

My brother had died a year earlier of a lethal form of brain cancer, at age thirty-three, leaving behind a young wife and baby daughter. I accompanied my brother and his wife through his diagnosis, treatment, and death. All along the way the doctors treating my brother at a major teaching hospital assured us that he would survive. After his death, I learned that his cancer is always lethal, but there were avenues we didn’t explore because we trusted his doctors to lead us down the right paths.

From this tragedy we found that we needed to be active participants in health care decisions, even to the point of reading the peer-reviewed literature the next time around. We learned that helping loved ones through a health crisis was not like taking a number at the deli counter. If research on PXE wasn’t being done, we couldn’t just wait until they called our number—they might never get to it. So we spent the weeks following our children’s diagnoses in medical school libraries, which aren’t exactly lay-friendly environments. We faced steep learning curves. Pat was a design engineer for a construction company and I was a college chaplain; neither of us had any medical background. We copied every article we could find and brought them home to read, quickly learning that we also would have to in- vest in medical dictionaries; encyclopedias; and biology, genetics, and epidemiology textbooks. Pat poured all of his energy into understanding the science behind the research—his way of coping as a distraught dad. And every glance at the lesions on our kids’ necks renewed our fear.

At the same time, our pediatrician discovered that a researcher at a major university nearby was conducting a research project to find the gene associated with PXE. She contacted the researcher, who came and took samples of our family’s blood. It gave us such hope to think that someone was working on this obscure disease. We were thrilled to participate, even though the researcher provided no informed-consent process. A few days later another researcher called from another major institution and asked for blood samples. We told him to get some from the first researcher. How shocked we were to find that they wouldn’t share and expected us to allow blood to be drawn from small children twice in one week. There was no central repository for the precious blood of people with this rare condition, whose numbers are 1 of every 25,000 Americans. We wondered if this was another indication of the inefficiency of the medical system.


Taking The Reins

Pat was relentless —learning the science as quickly as he could and bringing me along. Many nights he would read aloud passages from medical textbooks. We would bat the concepts back and forth, looking them up in medical dictionaries and encyclopedias. Sometimes we’d wake up in the morning to find we had fallen asleep with books and articles strewn around the bed. Some- times we’d fall asleep in tears after viewing photos of sagging skin or reading about the deaths of young people from heart and gastrointestinal complications.

We shielded the kids from this stuff as best we could.

As we waded through the literature, it became obvious that it did not present a clear picture and usually cited case studies that even we, with our limited knowledge, thought were extreme and unrepresentative of the condition. We also noticed that the few studies that included multiple patients contradicted one an- other. Pat’s construction design work relied on project management and coordination; he couldn’t understand why the same principles weren’t applied to medical research. We began to scheme about what we would do if we were man- aging research on this disease. It seemed to us that not only did PXE need a central repository for blood and tissue, it also needed a large cohort of affected people to give researchers a comprehensive understanding of the condition’s manifestations and progression.

We decided to meet with as many authors of PXE peer-reviewed literature as we could. Much to our surprise, everyone we contacted agreed to see us. Their perceptions about the condition ran the gamut, from one researcher who said, “PXE research is a rat hole—no one wants to do it, it isn’t worth it,” to some who were overly optimistic about the results of their efforts. We joined the only sup- port group for the condition and encouraged its founding physician to let us help set up a central registry and sample repository. He was adamantly opposed to both, not wanting to share information with other researchers because he had given much of his professional career to studying PXE. We struggled for several months to work with him, but it became increasingly apparent that his agenda and ours shared little overlap. One long night, Pat and I sat at the dining room table over a bottle of wine and agonized over what we had learned. We could not wait for one researcher to make headway while this disease progressed in our children. From our reading, Pat knew that just as he would coordinate the installation of plumbing and electricity in a building, so should the genetic studies, cell biology, animal models, and other aspects of the research progress on parallel tracks. Although it pained us greatly to do so (we had hoped that all affected people could work together), we started a new advocacy group for PXE. Pat’s skills and mine complemented each other. As he laid the groundwork for the scientific endeavors of the foundation, I began to build the support structure that affected people would need.

We contacted the Washington, D.C.–based Genetic Alliance, the world’s largest coalition of genetic advocacy groups. Its staff mentored us, introduced us to other lay leaders, and helped to focus our activities. With their help we were able to do a great deal in a short time. Gradually the new foundation, PXE International, took more and more of my time. I had been teaching part time and stopped doing anything except establishing the foundation. We enlisted Dr. Bercovitch and met every few nights, so that within six months we had created the PXE International Blood and Tissue Bank, laid the groundwork for an epidemiological study, coordinated dozens of volunteer outreach efforts around the world (from those of a nurse in South Africa to a mom in Romania), and begun to build the PXE International Research Consortium. This process was not easy. Only a combination of the Internet, other support groups, and Dr. Bercovitch’s help made all of this feasible. Our kids began to come to grips with PXE in their own way. Typical of children, they didn’t take it too seriously and instead did things like naming a spider “pseudoxanthoma elasticum,” proud to learn a Latin insect-naming technique!

Elizabeth and Ian have reacted to PXE in a remarkable way. They have skin lesions and the beginning signs of eye disease (although their vision is still fine). They feel most limited by a restriction on contact sports to protect their eyes. They have grown up aware that no one knows much about PXE’s progression but also with ideas about how to fight for a different future. They have testified three times before the House Appropriations Subcommittee on Labor, Health and Hu- man Services, and Education. At age eleven, Elizabeth recommended to the sub- committee that basic research be funded to benefit all conditions, not just hers. They both think that PXE has presented them with opportunities they never would have experienced. They believe that we will make a difference, so they don’t worry too much.


Getting Researchers On The Same Page

Watching the disease progress in our children provides us with the incentive to work long hours and craft novel solutions. Our blood and tissue bank is one result of our efforts. The need for such a bank came to us from several different directions: My ever-practical husband knew that we needed a commodity to leverage if we were to have a place at the ta- ble; competing interests of researchers don’t often allow widespread distribution of samples, which can slow research; and we knew that we would be able to offer affected people a centralized bank that would afford them something that they (and we) didn’t have before—confidentiality and anonymity.

Despite everything we had been through, however, new lows were yet to come. Soon after we started the PXE International Blood and Tissue Bank, the researcher in whose lab we banked our samples actively tried to thwart access to the bank by other researchers. We were appalled, maybe naïvely so, that researchers would put their needs for publications, funding, promotions, and tenure ahead of the needs of people living with disease. We apparently experienced an extreme exam- ple of this, but we and other groups have encountered variations of it repeatedly. Fortunately, this problem was counterbalanced by interactions with other re- searchers here and abroad, with whom real collaboration occurred. One of these relationships led to a joint application for the patent on the gene associated with PXE—the first time lay people in an advocacy group have applied for the patent. We consider ourselves stewards of the gene and know that the real issues will be played out in its licensing.

Our foundation sits at the juncture of research, education for affected people, and information for clinicians. We coordinate the PXE International Research Consortium, in which nineteen labs work through us with one another. This al- lows labs to do what they do best—excellent science—while preserving the ability to publish their own discoveries. At the same time, the labs together determine the dates when information sharing will take place. This also lets PXE International see gaps in the plan and make sure that all research phases are simultaneously fast-tracked. For example, we saw that the most difficult aspect for labs was information and sample collection from affected people and their families. In an ever-tightening regulatory climate in which institutional review boards are scrutinizing all human-participant research, our organization provides a firewall between researchers and research participants. This set up protects patient confidentiality and encourages participants’ involvement. It also allows us to re-contact participants when necessary for research while at the same time protecting them. Participants can engage in an unrushed decision-making process with us, deter- mining the risks and benefits of participating in the PXE International Blood and Tissue Bank, the epidemiological study that we sponsor, and other projects. They feel safe, knowing that we are all in the same boat—sharing the distress of living with PXE and searching for options.


Consumers As Catalysts

My work with PXE international has taught me that consumers can be central to the research endeavor. We can be a catalyzing force for translating research into the services we desperately need, such as

treatments, technologies to alleviate suffering, and clinical methods of dealing with the conditions. I now serve as president of the Genetic Alliance. This role enables me to work with other groups so that we leverage each other’s capacities to make a difference for our loved ones.

My family’s experience also has showed me that we need strong protections for research participants but not overly onerous regulations that make it impossible for researchers to have access to patients. In the same way that we know that our nation’s health care system needs overhauling, I am convinced that the research process in this country needs to undergo changes that will facilitate collaboration among labs and build large registries that allow discovery of the natural history and progression of disease.

We hope for a treatment that will slow down PXE and spare Elizabeth’s and Ian’s vision, but we know that the advances we seek are usually measured in generations, not lifetimes. For Pat, Elizabeth, Ian, and me, the journey has bonded us together in a profound way. Moreover, I know that when we shoulder our burdens with other advocacy groups, we will help to speed up research that will spare lives. It can’t happen fast enough.

Life as a numerator: Putting the person in personal genomics

Genetic Alliance and PXE International, USA


1. Introduction

While the science of human genomics is often focused on odds and probability, most of us do not experience risk that way.

I am a carrier of a mutation in ABCC6, as is my husband. Rather than experiencing the odds we would have children with the autosomal recessive condition pseudoxanthoma elasticum (25% each pregnancy) as an abstraction, our reality is having two of two children affected by PXE: our experience is 100%. Twice.

PXE affects 1 in 50,000 people. Our kids are the numerators. In 1994, when PXE was discovered in our then-very-young children, we felt not only overwhelmed by the prospect of taking care of them and anxious about the uncertainty of their futures, but isolated by the rare nature of their condition. Genetics? We didn't want to talk about it then and even if we did, we didn't have anyone with whom we could talk about it.

Today? Not so much. We—and thousands of others in similar circumstances—are bombarded with information from sequencing centers, clinics, research studies, and direct-to-consumer sites. And, spam fatigue notwithstanding, that's mostly to the good. Genetic disease is a long-tail problem that can only be solved if crowdsourcing rises to the occasion, that is, if families like mine and others contributing to and discussed in this issue are not alone. Precision medicine, biomedical re- search, and human health writ large all stand to benefit if the masses get involved. Indeed, I would argue that crowdsourcing is our only hope. Here I describe ways in which this is already happening and a vision for a future where it is standard practice.


2. Life on Mars

When our two children were diagnosed with PXE, it felt like we landed on Mars and were being chased by the grim reaper. Fear ripped through us, and no one was speaking words we could understand. This was not just because we could not hear through our fear, but because the world of biomedical research and disease characterization has an in- credibly esoteric and complex vocabulary. Even the sentence structures were complicated — all passive voice and past tense. It was as though the language—and by extension, our family—was not alive anymore.

As if it weren't terrifying enough to enter the stigma-ridden land of The Diagnosed, we immediately discovered an astonishing fact: scientists were not sharing. A few days after our kids' diagnoses, scientists from Harvard came to draw blood from us to use in the search for the causative gene. Two days after that, a separate group of scientists called from the Mt. Sinai Hospital in New York and asked for blood to work on 

PXE gene discovery. When we asked the second set of researchers to ask the first set for blood (and perhaps even collaborate), they expressed amazement that we would ask such a thing! We were struck by how the culture of science, particularly in biomedical research, had so colored the researchers' perspectives that they found our request preposterous. We felt both horrified and hopelessly naive.

But this was only our first foray into a world that left us surprised over and over: a world alien and offensive to us in our need. It seemed that publishing, getting tenure and getting promoted were more important than discovering what was causing PXE. We quickly got over our expectations for a rapid treatment, let alone a cure. What we couldn't get over were the lack of sharing and the intense competition among scientists. Twenty years on we're still not over it.

In 1995 we built a biobank and stored the samples at a major medical center. That was fine until we wanted to share those precious samples beyond that particular university. After notifying the researchers there that we were on our way to the laboratory to take one of 20 stored DNA aliquots per person, each of which we had deposited there our- selves, we arrived to find a lock on the freezer. Many months of arguing ensued, and we finally called the vice president of the medical center. He ordered the release of our samples. We informed the institution that we would be moving the entire collection of hundreds of samples. On the day we arrived to do that, we found the samples on a cart in the hallway — thawed and warm. We also saw that we were missing several aliquots per person. We took our room-temperature samples across town to freezer space we were renting. And then we took our anger and disappointment and channeled them into changing the system.

A few years later, I spent months negotiating the opportunity to do a natural history study of PXE at the National Institutes of Health. I offered to support the salary of a clinician researcher to do the study. Two glaring disconnects emerged. The first related to the study protocol. At this point, I had collected 900 fields of data on 4000 people living with PXE and knew something about its signs, symptoms and progression. But the investigators were adamant that they would focus on measuring phenotypic characteristics that had no correlation to PXE! They discounted our experience and our copious data. Second, they refused to let me be part of the study team. The “offer” was for me to sit in the back of the room; someone even made a joke that I could carry one of the researcher's briefcases. Their excuse for excluding me was that I was not credentialed in biomedical research. Nevermind that I had the equivalent of a PhD in PXE.

These experiences, and dozens of others, fueled a passion in me to lead an organization that was focused on the very people who need their suffering alleviated—one that was less concerned with academic status and more focused on improving the lives of patients and families. I became interested in practical tools that could be applied to any dis- ease or condition, that could help break down silos and enable sharing despite systems and bureaucrats that were and are often obstacles to the outcomes we seek.

Even more critical to me is trying to change the fundamental misalignments embedded in health care and biomedical research. When the President of the United States embraces the rhetoric of patient-and participant-centric research, we can safely say it has reached new heights. Indeed, it was music to my ears to sit in the East Wing in early 2015 and hear Barack Obama say “… I′m proud we have so many patients' rights advocates with us here today. They're not going to be on the sidelines. It's not going to be an afterthought. They'll help us design this initiative from the ground up, making sure that we harness new technologies and opportunities in a responsible way” (Anon., 2015).

As I write this nearly a year later, however, we have yet to see the deep and essential fundamental shift. We are behaving as though we believe that engagement and partnership have value, but we are still not able to articulate that value, and we are not able to tell the truth about the incentives that drive the biomedical research system. I sit in discussions about “patient-centricity” and wonder why the way we keep score remains rooted in tallies of publications and grant monies. I understand that for systems to change to realize beneficial health outcomes requires a long timeline. But I do not apologize for my impatience. Academia, regulators and even many in pharma seem to accept the ideas that: 1) developing drugs requires a decade; and 2) patients are passive data points in this process, i.e., they are to be collected, not consulted.


3. Strange attractors

In most of my encounters with the biomedical research system and its recent lust for big data – especially genotype and phenotype data – I′ve found that that those who champion “engagement” often see it as a useful euphemism for recruitment. At one level I understand this: I do not advocate for engagement for engagement's sake. But neither do I reduce it to a top-down call for increased sample size at all costs.

I think that this new intense interest in engagement, participation, and partnership is what chaos theorists David Ruelle and Floris Takens would call a “strange attractor” (Ruelle and Takens, 1971). The definition describes “basins of attraction within the system that lure the system into a new pattern of activity.” Engagement and participation, I hope and expect, will recenter the system and create authentic partnerships. Individuals, families and communities will take their rightful place as co-designers of new ways of engaging with their health.

In this regard, I am all in on an experiment. Together with Private Access, an innovative technology company, Genetic Alliance has built the Platform for Engaging Everyone Responsibly (PEER). It shifts the center of attention away from institutions, researchers, and even advocacy organizations, and toward individuals. Using PEER, each individual makes choices about data sharing, privacy, and access in a granular and dynamic way. It is our firm belief (and we have invited researchers to study this hypothesis) that if people make these choices for themselves, they will drive the market. They will aggregate themselves not in disease silos, but in pathways, phenotypes and symptoms that they strongly feel need attention and to which they are prepared to commit.

How does PEER work? In one example, we engaged with five sickle cell advocacy organizations and were able to learn from individuals living with sickle cell what mattered to them, and to deliver this information, along with patients' associated socioeconomic data, to the Food and Drug Administration for its Patient-Focused Drug Development program. We therefore extended the reach of the FDA's program to individuals who couldn't travel to metro DC to attend a hearing, or who were not able to post to the docket (the special web-based system that the government uses to catalog public comments).

In another example that is ongoing, ten disease advocacy organizations are working together in a boundary-free way to use the health information they collect across 15 diseases encompassing seemingly unrelated common (e.g., hepatitis, breast cancer) and rare (e.g., dyskeratosis congenita, Joubert syndrome) conditions. As a part of PCORnet, the national clinical research network being created by the Patient Centered Outcomes Research Institute (PCORI), these organizations are working to define research priorities and advance them together. This example is just one of 20 Patient-Powered Research Networks (PPRN) in PCORI that seek to run dozens of experiments on what constitutes true participant-centric research, how to build a network that will shift the current paradigm, and how to develop more robust strange attractors, all while measuring their impact on the current research and services system.

Plenty of obstacles and challenges to these sorts of approaches remain. Large-scale research on human beings is a young pursuit. And formal governance of it is even younger. Most of the same incentives that kept researchers from sharing samples and data in 1994 are still in place. And while patient-and participant-advocates are more frequently invited to discussions surrounding research initiatives, we are still routinely marginalized: we have a seat at the table but rarely do we get to have any meaningful say about what's on the menu or who should be invited to the meal. I hear rhetoric calling for “bridging to ‘those’ people” and “inviting them in.” But to my ears those terms are harsh and grating: they perpetuate an “us” and a “them.” We are all us and we are all them.


4. Street cred

The “us and them” frame is more than a linguistic peeve. In recent years, those of us who have been at this for a while have found our legitimacy called into question. There are those, even within the patient and participant advocacy movements, who now routinely discount what some of us do. Some claim that we are not ‘true patients’ because we have peer-reviewed papers, conduct research, lead large organizations and/or work to influence policy at multiple levels—we are “them.” In ways that I find both saddening and ironic, it seems that our very efforts have somehow sowed distrust. We are suddenly written off as having Stockholm syndrome or not truly representing patients.

More than any slight from a researcher ever could, hearing this from fellow advocates hurts. I am still, first and foremost, mother to my two children who live with a genetic condition. I would much rather my family not live life as a numerator, but I—like all families coping with any of the thousands of serious health conditions, be they common or rare—have no choice. All we can do is fight.

Meanwhile, my daughter has succeeded me as the executive director of PXE International. She has doubled the organizational budget and doubled the number of affected individuals enrolled in two short years. Her mission, like mine, remains unchanged: it is not to have a scientific career or access to power, but to alleviate suffering—her own, her brother's, and the thousands like them.

When we have done that for the larger community of numerators, we will gladly shut off the lights and go home.

Barbara Drewicz

Barb is a native of Southeastern Pennsylvania where she currently resides with her husband, Mark. She has two adult daughters and four grandchildren. She graduated from West Chester University with a BA in Psychology and an M.Ed in School Counseling. 

She has had a long and rewarding career in the Human Services field in both private and public sectors, more recently in the public education system serving for over 25 years as lead primary school counselor and coordinator.  She has served as Board Secretary and County representative with the Pennsylvania School Counselor Association for over twenty years, retiring in 2014.

First and foremost she is the mother of a daughter with PXE, which is the genesis of her connection to PXE International.  Since her daughter was first diagnosed in 2001, she and her family have been on a journey to educate & inform themselves with the most accurate, research-based information about this unique and challenging condition.  Finding both knowledge and support within this organization fulfilled a need to both help her daughter and contribute through volunteering. 

Since being on the board, Barbara has had the opportunity to speak with many PXErs and has been continually inspired by this community’s positivity, optimism and personal stories of fortitude in the face of their daily challenges.  Likewise, she feels the integrity, dedication and hard work of the shoe-string PXE staff and its leaders, challenges us all to do more to help pursue its mission of research in pursuit of treatment and cure to end the burden of PXE in our world.

Joe Maas

Treasurer, PXE International
JTM Provisions, Harrison, OH


 Joe Maas was born and raised in Cincinnati, Ohio where he continues to live today.

Joe is married to Robin and has three grown children, two sons and a daughter. He attended the University of Cincinnati in Ohio and received a BA in pharmacology. Although he is a licensed pharmacist in Ohio, he has not worked in the field since 1998. He now helps to run a very successful food processing business he owns with his three brothers.

In 1999 his son Kevin was diagnosed with pseudoxanthoma elasticum (PXE). An Internet search on the subject brought up PXE International, which he contacted immediately. During the first days, as he came to terms with the diagnosis, he spoke to Pat and Sharon Terry several times. It helped to speak to other parents in the same situation. He joined the foundation and attended the conference in Boston in June 2000. His involvement included financial support and keeping up with current information. While attending the conference in Oakland, CA in 2002, he was flattered when Sharon asked him to join the board.

His vision for the board is to continue to search for a treatment for PXE. His medical education background allows him to follow trial studies and understand the technical terminology used in their reports. This skill will allow him to evaluate the proposed medical studies and help to direct the funds available for research. He is excited about the studies being conducted and is hopeful that a treatment will be found soon. He is also proud to be a part of PXE International because of their work concerning the moral issues surrounding genetic research. He can appreciate the importance of a patient´s privacy and supports PXE International taking a stand to foster political policy regarding how genetic information is handled.

Through his association with PXE International and the Terrys, Joe has come to understand that his responsibilities extend beyond his own child. He recognizes his role on the board is to help people who are currently affected with the symptoms of PXE, and those yet to come.

Joe also serves on the boards of several charitable entities in the Cincinnati area as well as the boards of several food industry organizations.

Kathy Hersey

Kathy Hersey was born and raised in Garden City, NY and now resides in Westchester County, NY. She is married to Robert and has three sons, Rob, Austin and Jonathan. Kathy's son Rob was diagnosed with PXE around 1996. The Hersey's met the Terry's shortly after Sharon and Pat founded PXE International. It was so relieving to find such great support with such an isolating disease. PXE International has grown over the years and we have met so many wonderful people. PXE International has become like a second family to us.

Kathy and Robert became grandparents in October 2018. Rob and his wife Christine welcomed their first child James Hersey. He brings the whole family so much joy.

With the help of Kathy's family and the Wall Street community, fundraising efforts began. Since 2000, Kathy's brother Joe and his band, The Rockbrokers, have raised money for PXE International in the U.S. and abroad, donating $650,000. The Rockbrokers played at the PXE International 15th anniversary conference in Washington D.C. in September 2010.

Kathy hopes to continue to support the board, and looks forward to new and exciting research coming from PXE International.

Patrick Terry

President, PXE International


Patrick Terry brings the wisdom of a perspective forged from personal experience and extensive work in the lay advocacy (patient) community. Following the diagnosis of their two children with a rare condition, pseudoxanthoma elasticum (PXE) in 1995, Patrick and his wife, Sharon, founded PXE International, a dynamic lay organization that initiates, coordinates and funds research, as well as worldwide patient support. In the years since, PXE International has grown to include an international 19 lab consortium, 52 support offices worldwide, a private blood and tissue bank, and a database registry of thousands of affected individuals. The culmination of his effort toward global coordination of research has led to tremendous scientific advances for PXE and related diseases.

Patrick has worked with many professional medical organizations, and is on the professional advisory board of the Genetic Alliance of Washington, DC. His participation in biomedical research in our nation's capital has been instrumental in the overall increased funding for the NIH as well as recognition of the power and importance of lay advocacy groups. In all of his work he has emphasized the importance of the consumer as a full and active partner in the collaborative process of genomics research and healthcare services. His vision for creating a new paradigm for empowering consumer involvement in research has not only been brought to fruition in the success of PXE International, but has been embodied in mentoring many other lay advocacy organizations.

Patrick is a social entrepreneur who has founded a series of innovative philanthropic, research, and commercial organizations based on the life sciences, applied technology, and social-network theory. He is the co-founder of Genomic Health [NASDAQ: GHDX], and former Director at the pioneering personalized medicine company based in California. He is a lay person – his scientific, technical, and medical knowledge is all self-taught. He has published dozens of peer-reviewed scientific papers, articles, and book chapters in the fields of genetics, translational research, and personalized medicine. Some of his past activities included leadership positions on numerous trade associations, professional societies, corporate boards, and federal advisory bodies. He has experience doing hands-on bench science, coordinating human genetics research, conducting basic research on rare diseases, and managing a life sciences patent portfolio. He has received many honors and awards in the business and scientific communities in the U.S. and internationally. He has dedicated his career to helping people and advancing a patient-centered perspective in research, product development, and translational medicine.

Patrick has also founded the following organizations: Personalized Medicine Coalition, 21st Century Medicine Coalition, Genomic Health, Genetic Alliance BioBank, Technic Solutions, International Genetic Alliance, BioLogos Foundation, and Grand Therapeutics.

Patrick now works as Chief Commercial Officer at Claritas Genomics in Boston, Massachusetts.
