Abstract
Discovering the genetic basis of a particular disease is not only of great interest to the medical community; private health insurers are also anxiously awaiting the results of genetic linkage studies. Apart from the scientific value of DNA studies, the results of genetic linkage research are relevant to health care delivery in two principal ways. First, identifying the genetic origin of a disease may allow doctors to detect the disease earlier. If doctors know that an individual is genetically predisposed to a particular disease, then health care providers can increase screening efforts and watch for early symptoms. Second, if an individual has a genetic predisposition to a particular disease, health care providers may employ preventive or “prophylactic" measures to reduce or eliminate the risk of developing the disease or condition to which the individual is genetically predisposed. Genetic linkage studies will soon allow more individuals to learn of their own genetic predispositions to certain diseases. Currently genetic predisposition tests (both pedigrees of family history and DNA analysis) can indicate that an individual is at high risk for developing a disease.
