Genes associated with various forms of short QT syndrome

Gene	OMIM gene	Disease	OMIM disease	Inheritance	Function
KCNH2	152427	SQT1	609620	AD	Pore-forming subunit of voltage-gated inwardly rectifying K+ channel
KCNQ1	607542	SQT2	609621	AD	Repolarizes cardiac action potential
KCNJ2	600681	SQT3	609622	AD	Establishes action potential and excitability of neurons and muscles

AD=autosomal dominant; AR=autosomal recessive
