Genes affected
ABCC9 (HGNC:60): (ATP binding cassette subfamily C member 9) The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily which is involved in multi-drug resistance. This protein is thought to form ATP-sensitive potassium channels in cardiac, skeletal, and vascular and non-vascular smooth muscle. Protein structure suggests a role as the drug-binding channel-modulating subunit of the extra-pancreatic ATP-sensitive potassium channels. Mutations in this gene are associated with cardiomyopathy dilated type 1O. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2011]

Variant summary: The ABCC9 c.1056C>T (p.Tyr352Tyr) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. Mutation taster predicts a damaging outcome for this substitution. This variant was found in 88/120960 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.00771 (80/10376). This frequency is about 308 times the estimated maximal expected allele frequency of a pathogenic ABCC9 variant (0.000025), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Considering the high prevalence of the variant in the general population, it was classified as benign. -
