The gene which is affected in Andersen Syndrome (LQT7) is: a. KCNH2 b. KCNQ1 c. SCN5A d. KCNJ2 Answer: d In Andersen syndrome, KCNJ2 which codes for Ik1 potassium channel (Kir2.1) is affected by a loss of function mutation. This results in a reduced outward potassium current. Andersen syndrome is characterised by long QT, periodic [...]
