Low penetrance in the long-QT syndrome: clinical impact.

Circulation - 2 Feb 1999

Priori S G, Napolitano C, Schwartz P J

Abstract excerpt

BACKGROUND: It is still currently held that most patients affected by the long-QT syndrome (LQTS) show QT interval prolongation or clinical symptoms. This is reflected by the assumption in linkage studies of a penetrance of 90%. We had previously suggested that a larger-than-anticipated number of LQTS patients might be affected without showing clinical signs. We have now exploited the availability of molecular...
