Variant Summary: The c.671-8A>G variant involves the alteration of a non-conserved nucleotide resulting in an intronic change. This variant is located at a position that is not widely known to affect splicing, 3/5 splicing prediction programs via Alamut predict no significant effect on splicing, and mutation taster predicts the variant to be a polymorphism. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.012%, predominantly observed in the East Asian subpopulation at a frequency of 0.18%. This frequency exceeds the maximal expected allele frequency for a pathogenic variant in BRCA1 (0.10%), suggesting this is a benign polymorphism found primarily in population(s) of East Asian origin. The variant has been reported in multiple databases to co-occur in individuals with pathogenic BRCA1 variants including two patients with c.2296_2297delAG, p.Ser766X (UMD), one patient with c.68_69delAG, p.Glu23ValfsX17 (UMD), and one patient with c.188T>A, p.Leu63Ter (BIC). Taken together, the multiple co-occurrences with pathogenic variants along with the intronic nature of the variant and the relatively high frequency in the East Asian population, this variant was classified as Benign.

This 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). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
