There is going to be a special audiocast at DNA.com on Wednesday October 25, 2000 at 2pm EST.
Their guest will be Jeff Vance, M.D., Ph.D.
I attended their Huntington's chat and it was very informative.
here's the info
Parkinson's disease is a disorder of brain cells. In Parkinson's disease, cells in
special parts of the brain progressively stop working. These cell malfunctions
occur in different patterns from person to person, which explains the many
different patterns of symptoms in Parkinson's disease. For reasons unknown,
cells that control movement are most often affected. Diagnosing Parkinson's
disease is difficult; a door-to-door survey in Europe showed that 24 percent
of all people with Parkinson's disease had not been diagnosed, and autopsy
studies have shown that about 25 percent of people who are diagnosed with
Parkinson's disease do not actually have it.
The cause of Parkinson's disease is not entirely known, but there is a strong
genetic component. One study found that close relatives of Parkinson's
disease patients were more than twice as likely to have signs of the disease
as the rest of the population. However, there are also strong environmental
factors. About 75 percent of people with Parkinson's disease do not have a
family history of the disorder, and there are certain toxins that have directly
caused it in some cases. Dr. Jeff Vance, director of Duke University's Udall
Center, a Parkinson's Disease Research Center, will discuss the genetics of
this debilitating disease.
Jeff Vance, M.D., Ph.D., is an associate professor in the Department of
Genetics at Duke University Medical Center in Durham, N.C. There, he is also
director of the Genomic Research Laboratories at the Center for Human
Genetics, associate professor with tenure in the Division of Neurology. Also,
Vance directs the Udall Center at Duke University, which is one of eight new
Parkinson's Disease Research Centers for Excellence supported by the
National Institute of Neurological Disorders and Stroke. Dr. Vance earned his
Ph.D. in medical genetics from Indiana University in Bloomington before
receiving his medical degree from Duke University Medical School.
