Genes affected
BRIP1 (HGNC:20473): (BRCA1 interacting helicase 1) The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.

Variant summary: BRIP1 c.3149C>A (p.Thr1050Asn) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6.9e-05 in 1614186 control chromosomes in the gnomAD database (v4.1 dataset), including 2 homozygotes. The variant was observed predominantly within the South Asian subpopulation at a frequency of 0.00085, which is approximately 13.6 fold of the estimated maximal expected allele frequency for a pathogenic variant in BRIP1 causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (6.3e-05). The variant, c.3149C>A, has been reported in the literature in individuals affected with breast-/ovarian cancer and other tumor phenotypes (e.g. Singh_2018, Moyer_2020, Sahin_2022), however in at least one of these patients a co-occurrence with an (unspecified) pathogenic BRCA1/2 mutation was noted (Moyer_2020). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 29470806, 31822495, 35089076). ClinVar contains an entry for this variant (Variation ID: 140825). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
