Overview
This variant results from a G514A substitution in the KCNJ2 gene ( a change from aspartic acid to asparagine at position 172 (D172N))[1]. This causes a defect in the gene coding for the inwardly rectifying Kir2.1 (I(K1)) channel. The ECG shows asymmetrical T waves. These patients have an increased risk for re-entry arrhythmias.
