Genes affected
ABCA7 (HGNC:37): (ATP binding cassette subfamily A member 7) The 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 intra-cellular 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. This full transporter has been detected predominantly in myelo-lymphatic tissues with the highest expression in peripheral leukocytes, thymus, spleen, and bone marrow. The function of this protein is not yet known; however, the expression pattern suggests a role in lipid homeostasis in cells of the immune system. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.68).
BP6
Variant 19-1042748-A-G is Benign according to our data. Variant chr19-1042748-A-G is described in ClinVar as Benign. ClinVar VariationId is 3043028.Status of the report is no_assertion_criteria_provided, 0 stars.
BP7
Synonymous conserved (PhyloP=-0.43 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000125 (19/152228) while in subpopulation SAS AF = 0.00311 (15/4830). AF 95% confidence interval is 0.00191. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 7 Unknown gene
