Genes affected

ABCA13 (HGNC:14638): (ATP binding cassette subfamily A member 13) In human, the ATP-binding cassette (ABC) family of transmembrane transporters has at least 48 genes and 7 gene subfamilies. This gene is a member of ABC gene subfamily A (ABCA). Genes within the ABCA family typically encode several thousand amino acids. Like other ABC transmembrane transporter proteins, this protein has 12 or more transmembrane alpha-helix domains that likely arrange to form a single central chamber with multiple substrate binding sites. It is also predicted to have two large extracellular domains and two nucleotide binding domains as is typical for ABCA proteins. Alternative splice variants have been described but their biological validity has not been demonstrated.[provided by RefSeq, Mar 2009]

Ambry Genetics

Apr 28, 2023

The c.71T>A (p.V24D) alteration is located in exon 2 (coding exon 2) of the ABCA13 gene. This alteration results from a T to A substitution at nucleotide position 71, causing the valine (V) at amino acid position 24 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
