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.

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. -

The BRIP1 p.Val390= variant was not identified in the literature. The variant was identified in dbSNP (rs754755989) as “with likely benign allele” and ClinVar (interpreted as "likely benign" by Invitae, Color and Ambry Genetics). The variant was identified in control databases in 13 of 245,134 chromosomes at a frequency of 0.00005 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: and South Asian in 13 of 30,722 chromosomes (freq: 0.0004). The variant was not observed in the African, Other, Latino, European, Ashkenazi Jewish, East Asian and Finnish populations. The p.Val390= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
