Genes affected

ABCA9 (HGNC:39): (ATP binding cassette subfamily A member 9) This gene is a member of the superfamily of ATP-binding cassette (ABC) transporters and the encoded protein contains two transmembrane domains and two nucleotide binding folds. 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 gene is a member of the ABC1 subfamily and is clustered with four other ABC1 family members on chromosome 17q24. Transcriptional expression of this gene is induced during monocyte differentiation into macrophages and is suppressed by cholesterol import. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 20, 2021

The c.4529G>C (p.S1510T) alteration is located in exon 36 (coding exon 35) of the ABCA9 gene. This alteration results from a G to C substitution at nucleotide position 4529, causing the serine (S) at amino acid position 1510 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
