Genes affected
ABCA3 (HGNC:33): (ATP binding cassette subfamily A member 3) 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. The full transporter encoded by this gene may be involved in development of resistance to xenobiotics and engulfment during programmed cell death. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 16-2319773-G-A is Benign according to our data. Variant chr16-2319773-G-A is described in ClinVar as Benign. ClinVar VariationId is 162673.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.37 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0165 (2516/152160) while in subpopulation SAS AF = 0.0214 (103/4816). AF 95% confidence interval is 0.0201. There are 34 homozygotes in GnomAd4. There are 1284 alleles in the male GnomAd4 subpopulation. Median coverage is 30. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 34 AR gene
