A Growing Array of Tests to Check If Women Are Carriers for Mostly Rare Diseases
Scientists keep identifying new gene mutations, or variations, associated with specific diseases. Advances in DNA technology allow companies to quickly screen large numbers of people, using saliva or blood samples, to determine if parents could pass the genetic variations to their children.
Counsyl offers tests that aim to detect heightened genetic risk for at least 98 different diseases, for between $599 and $999. Another company, Gene by Gene Ltd., of Houston, plans in the next few months to introduce First Look, a test billed as the most comprehensive on the market that can screen for more than 300 diseases. The company expects the price could be close to $1,500.
