Genes affected

ABCA5 (HGNC:35): (ATP binding cassette subfamily A member 5) 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 intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This encoded protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. This gene is clustered among 4 other ABC1 family members on 17q24, but neither the substrate nor the function of this gene is known. Alternative splicing of this gene results in several transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 10, 2023

The c.4234G>C (p.V1412L) alteration is located in exon 31 (coding exon 31) of the ABCA5 gene. This alteration results from a G to C substitution at nucleotide position 4234, causing the valine (V) at amino acid position 1412 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
