Genetic Testing Background

Over the past 15 years, the medical genetics community has witnessed a rapid rise in the identification of disease-related genes and the subsequent availability of genetic tests that detect disease or an individual's carrier risk of disease.

Currently, more than 4,000 genetic diseases are known, and over 900 genetic tests are available through diagnostic laboratories. Some tests identify chromosome abnormalities such as aneuploidy and rearrangements. Other tests detect the presence of inherited gene mutations and can confirm a suspected diagnosis of disease, determine an individual's carrier state, or predict future disease. Genetic tests are also performed to identify acquired gene mutations in cancerous cells.
