Genes affected
ABCA1 (HGNC:29): (ATP binding cassette subfamily A member 1) 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, White). This protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. With cholesterol as its substrate, this protein functions as a cholesteral efflux pump in the cellular lipid removal pathway. Mutations in both alleles of this gene cause Tangier disease and familial high-density lipoprotein (HDL) deficiency. [provided by RefSeq, Sep 2019]

Likely benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 07, 2016Variant summary: The ABCA1 c.5039G>A (p.Arg1680Gln) variant involves the alteration of a conserved nucleotide. 4/5 in silico tools predict a damaging outcome for this variant. This variant was found in 53/136884 control chromosomes at a frequency of 0.0003872, which is approximately 31 times the estimated maximal expected allele frequency of a pathogenic ABCA1 variant (0.0000125), suggesting this variant is likely a benign polymorphism. This variant has been reported in individuals with both high and low level of HDL-C, all without strong evidence for causality. The variant of interest has not, to our knowledge, evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as likely benign until more evidence becomes available. -

Hypoalphalipoproteinemia, primary, 1 Benign:1
Likely benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
