Genes affected

ABCB9 (HGNC:50): (ATP binding cassette subfamily B member 9) The membrane-associated 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 MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This family member functions in the translocation of peptides from the cytosol into the lysosomal lumen. Alternative splicing of this gene results in distinct isoforms which are likely to have different substrate specificities. [provided by RefSeq, Jul 2011]

Ambry Genetics

Nov 13, 2023

The c.1780C>T (p.R594C) alteration is located in exon 10 (coding exon 9) of the ABCB9 gene. This alteration results from a C to T substitution at nucleotide position 1780, causing the arginine (R) at amino acid position 594 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
