Genes affected

ABCB10 (HGNC:41): (ATP binding cassette subfamily B member 10) 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. The function of this mitochondrial protein is unknown.

The c.1216G>A (p.G406R) alteration is located in exon 6 (coding exon 6) of the ABCB10 gene. This alteration results from a G to A substitution at nucleotide position 1216, causing the glycine (G) at amino acid position 406 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
