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.

Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMar 16, 2017Variant summary: The BRIP1 c.36G>T (p.Gly12Gly) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. The variant lies within a P-loop domain, a helicase domain, a helicase-like DEXD box domain, and a helicase superfamily ATP-binding domain of the protein (InterPro), though none of these domains are listed in the NCBI Conserved Domain database at the variant location. One in silico tool predicts a damaging outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant does not signifcantly affect ESE sites at the locus. However, these predictions have yet to be confirmed by functional studies. This variant was found in the large control database ExAC in 31/121030 control chromosomes, exclusively observed in the European (Non-Finnish) subpopulation at a frequency of 0.000466 (31/66568). This frequency is about 7 times the estimated maximal expected allele frequency of a pathogenic BRIP1 variant (0.0000625), suggesting this is likely a benign polymorphism found primarily in populations of European (Non-Finnish) origin. Multiple clinical diagnostic laboratories/reputable databases have conflicting classifications for this variant, most of which are benign or likely benign (benign [2x], likely benign [3x], and uncertain significance [2x]). To our knowledge, the variant of interest has not been reported in affected individuals via publications, nor has it been evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -
