Genes affected

ABCC3 (HGNC:54): (ATP binding cassette subfamily C member 3) 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. The specific function of this protein has not yet been determined; however, this protein may play a role in the transport of biliary and intestinal excretion of organic anions. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 12, 2024

The c.890C>T (p.P297L) alteration is located in exon 8 (coding exon 8) of the ABCC3 gene. This alteration results from a C to T substitution at nucleotide position 890, causing the proline (P) at amino acid position 297 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
