Not associated with phenotype in OMIM or in Gen2Phen. Listed as a candidate gene for Short QTCreated: 15 Nov 2018, 12:10 p.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown

Would likely be gain of function mutations.
The rationale for including this is that whilst mutations have not yet been detected, it is a candidate gene. ABCC9 encodes Sur2A and Sur2B which are components of the K(ATP) channel.
Templin et al (PMID: 21383000) included it in a SQTS panel as a candidate gene along with KCNJ2 (another component of the KATP channel.
A number of experimental studies have shown that K(ATP) channel activation gives a SQTS phenotype.
