CALM3 (Calmodulin-3) variants and mutations

CALM3 (also known as Calmodulin-3) is a human protein-coding gene encoding a calmodulin-3 protein. It produces the same highly conserved calmodulin protein as CALM1 and CALM2, allowing calcium-dependent regulation of many cardiac and neuronal proteins. Pathogenic missense variants can cause severe inherited arrhythmia syndromes collectively termed calmodulinopathies. This analysis covers 231 CALM3 variants and mutations. Of these, 68% have computational variant effect predictions. Disease context includes long QT syndrome 16, long QT syndrome 1, and bacterial infectious disease. Example CALM3 variants include M1?, A2S, and A2A.
