The overlapping syndromes, concomitant Brugada-like (atypical) and SQTS, in a single patient with the same mutation and positive family history of SCD are reported in less reported variants including voltage-dependent calcium channel subunits (CACNA2D1, CACNA1C, CACNB2)43 and sodium channel protein (SCN5A)45. This evidence concerns the gene CACNA2D1 and Familial short QT syndrome.
