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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineSep 22, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Pro1531Ser va riant in ABCC9 has not been previously reported in individuals with cardiomyopat hy, but has been identified in 6/10386 of African chromosomes by the Exome Aggre gation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs142875103). Pro line (Pro) at position 1531 is not conserved in mammals or evolutionarily distan t species and >15 birds and reptiles carry a serine (Ser) at this position, rais ing the possibility that this change may be tolerated. In summary, while the cli nical significance of the p.Pro1531Ser variant is uncertain, these data suggest that it is more likely to be benign. -
