Crusade for a Cure

Battle for gene control

WebMD Feature

Sept. 15, 2000 -- At first glance, the Terry family of Massachusetts doesn't seem either formidable or unusual. Sharon is a short woman with a master's degree in religious studies. Her husband, Patrick, is a soft-spoken engineer who runs a construction company and carries a Palm Pilot and beeper on his belt. Elizabeth, age 12, looks like her dad and loves Harry Potter; her brother Ian is a gregarious 11-year-old who likes to hang out at the beach with his pals. They live in a small house on a shady corner in a sleepy suburb of Boston.

But take a walk through the Terry's kitchen and you'll see a back room jammed with files, phones, faxes, and computers. Look closely at Elizabeth and Ian and you might notice a series of small red bumps on their necks and faces -- the only sign that they are afflicted with a genetic disorder called pseudoxanthoma elasticum, or PXE. And ask Sharon or Pat about PXE, and you'll find out why they've turned their house into a war room and themselves into savvy activists who almost single-handedly have pushed this disease onto the research radar.

The Terry children were diagnosed with PXE in 1994, when Sharon took Elizabeth, then 7, to a dermatologist to check out a rash on her neck. Ian, then 6, came along for the visit. Before the appointment was over, Sharon learned that one -- and probably both -- of her children had this mysterious and dire disease. The doctor had no idea how it would progress or how serious its implications would be.

"All I heard was two big words, the first one with 'oma' in it," Sharon says. "And then the doctor was looking at my son and telling me he probably had the same thing."

As Sharon and her husband soon learned, PXE is a rare genetic disorder that affects connective tissues throughout the body, resulting in skin lesions and sometimes causing dramatic degeneration of vision. It's also been linked to heart attacks and, in some cases, premature death. At the time the Terry children were diagnosed, the disorder was thought to strike one in 100,000 people, and with frequently fatal results. (Experts now think the disease is both more common -- and less deadly -- than originally believed, striking between one in 25,000 and one in 50,000 people.)

A Stunning Diagnosis

For the Terrys, this was stunning news, and like many families facing a health crisis, they wanted more than support -- they wanted a cure. But instead of waiting passively for answers, they took action, setting up their own nonprofit organization, PXE International, to get the process moving. In just four years, they've raised tens of thousands of dollars, established an international database, and recruited more than 1,000 patients in 36 countries to donate tissue samples for research, as well as the scientists to study them.

The Terrys have also made legal news. Beyond getting studies underway, they wanted a say in how the results might be used. So they did what only a handful of other patients have done before: They negotiated for a share of the patent rights and drug profits that might come from the samples their children and other patients provided. And they drafted contracts that gave PXE International a voice in the research it was helping to create.

In taking these steps, the Terrys showed a level of shrewdness that's almost unheard of among consumers, says Mary Davidson, executive director of the Genetic Alliance in Washington, D.C. "Sharon and Pat knew what they wanted, and they figured out how to accomplish it."

This year, their efforts hit pay dirt when researchers -- working with this donated tissue -- identified the gene that causes PXE, a finding that could lead to the development of a screening test that can identify carriers of the gene. This kind of speed in the lab is all but unheard of, Davidson says. "But the Terrys have that combination of creativity and enthusiasm that can push the system into overdrive," she says.

From Worried Parents to Focused Crusaders

From the day of that first appointment in 1994, the Terry family has been on an emotional roller coaster. Their first response was to read everything they could find about the disease, emerging with a slanted and scary picture. "As soon as we got the diagnosis, we opened the Merck Manual and read about PXE," says Pat. "It was horrific: certain blindness, early death." They also started dealing with the psychological pain that faces any parent in this situation, including the misplaced guilt that can go along with passing on an inherited disorder.

They also learned, though later, that one in every 40 to 70 people carries the PXE gene. Because the gene is usually recessive, carriers -- those with one copy of the PXE gene and one normal one -- have no symptoms. Therefore, most people, including the Terrys, don't know they have it. But when two carriers come together and have a child, that child faces a 25% chance of developing the disorder.
