Genes affected

GAS8 (HGNC:4166): (growth arrest specific 8) This gene includes 11 exons spanning 25 kb and maps to a region of chromosome 16 that is sometimes deleted in breast and prostrate cancer. The second intron contains an apparently intronless gene, C16orf3, that is transcribed in the opposite orientation. This gene is a putative tumor suppressor gene. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.023851693).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000538 (82/152388) while in subpopulation AFR AF= 0.0018 (75/41604). AF 95% confidence interval is 0.00147. There are 0 homozygotes in gnomad4. There are 33 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 11 of the GAS8 protein (p.Lys11Glu). This variant is present in population databases (rs146066553, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with GAS8-related conditions. ClinVar contains an entry for this variant (Variation ID: 475563). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
