Added comment: Different mutations have different degrees of penetrance: N588K and T618I are 100% penetrant; some others have incomplete penetrance.

The mutations are gain-of-function mutations that increase cardiac I(Kr) and abbreviate cardiac action potential duration leading to shortened QT intervals

KCNH2 aka hERG (human Ether-a-go-go-Related Gene). Gene product: hERG or Kv11.1
