Overview

Catecholaminergic polymorphic ventricular tachycardia can be classified based upon the underlying pathogenic mutation.

CPVT may be classified based upon the underlying pathogenic mutation into the following subtypes:^[1]

Type	OMIM	Gene	Protein	Mode of inheritance	Locus
CPVT1	604772	RyR2	Ryanodine receptor 2	Autosomal dominant	1q42.1-q43
CPVT2	611938	CASQ2	Calsequestrin 2	Autosomal recessive	1p13.3-p11
CPVT3	614021	Unknown	–	Autosomal recessive	7p14–p22
CPVT4	614916	CALM1	Calmodulin 1	Autosomal dominant	14q32.11
CPVT5	615441	TRDN	Triadin	Autosomal recessive	6q22.31
