Jennifer Jones Austin is a complete stranger to me. But in the coming months you’re going to hear me talk a great deal about people just like her. At the age of 41 this mother of two is suffering from leukemia. Though with this serious form of cancer Jennifer’s prospects for survival will increase dramatically if she receives a bone marrow transplant. But first she needs a donor. A successful transplant requires a very specific tissue match. The most likely donor candidate will be a person who shares her genetic ancestry. Unfortunately, African-Americans represent only 2 percent of the pool of registered donors in the United States. The chances of Jennifer finding a match are quite low.
