Genes affected

ABCC12 (HGNC:14640): (ATP binding cassette subfamily C member 12) This gene is a member of the superfamily of ATP-binding cassette (ABC) transporters and the encoded protein contains two ATP-binding domains and 12 transmembrane regions. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies: ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White. This gene is a member of the MRP subfamily which is involved in multi-drug resistance. This gene and another subfamily member are arranged head-to-tail on chromosome 16q12.1. Increased expression of this gene is associated with breast cancer. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.3547G>A (p.V1183M) alteration is located in exon 25 (coding exon 25) of the ABCC12 gene. This alteration results from a G to A substitution at nucleotide position 3547, causing the valine (V) at amino acid position 1183 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
