Genes affected

ABCA10 (HGNC:30): (ATP binding cassette subfamily A 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 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. [provided by RefSeq, Jul 2008]

The c.4238T>C (p.M1413T) alteration is located in exon 36 (coding exon 33) of the ABCA10 gene. This alteration results from a T to C substitution at nucleotide position 4238, causing the methionine (M) at amino acid position 1413 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
