PFHB1A: progressive familial heart block, type 1A, LQT3: long QT syndrome 3, CMD1E: dilated cardiomyopathy 1E, BRGDA1: Brugada syndrome, and RWS: Romano–Ward syndrome.
Disease names are reported as OMIM IDs.
NC: indicates no significant change.
Indicates a discrepancy between multiple mutations or references for the same gating property.
