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 submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	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. -

clinical testing

Sep 27, 2022

The BRIP1 c.2830C>G variant is predicted to result in the amino acid substitution p.Gln944Glu. This variant was reported in individuals with a personal and/or family history of breast cancer, pancreatic ductal adenocarcinoma, and gastric cancer (Cao et al. 2009. PubMed ID: 18483852; Kim et al. 2016. PubMed ID: 26790966; Cremin et al. 2020. PubMed ID: 32255556, Supplementary Table 3; Suzuki et al. 2020. PubMed ID: 32426482, Supplementary Table S6). Functional studies found that although BRIP1 (aka FANCJ) Q944E variant protein levels were comparable to wild type, the Q944E variant protein was defective in interacting with BRCA1 protein (Nath et al. 2017. PubMed ID: 28911102). This variant is reported in 0.24% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-59763272-G-C) and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from benign to uncertain significance (https://www.ncbi.nlm.nih.gov/clinvar/variation/128180/). Although we suspect this variant may be benign, at this time its clinical significance is uncertain due to the absence of conclusive functional and genetic evidence. -
