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: Likely_benign. The variant received -6 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_noAF, Cadd, MutationAssessor, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.35756385).

BP6

Variant 19-1041541-T-C is Benign according to our data. Variant chr19-1041541-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 715315.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000404 (59/1461236) while in subpopulation AMR AF = 0.0013 (58/44718). AF 95% confidence interval is 0.00103. There are 0 homozygotes in GnomAdExome4. There are 21 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
