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]

The c.479A>G (p.N160S) alteration is located in exon 6 (coding exon 6) of the ABCA13 gene. This alteration results from a A to G substitution at nucleotide position 479, causing the asparagine (N) at amino acid position 160 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
