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	curation	Sema4, Sema4	May 19, 2021	- -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	May 07, 2018	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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 02, 2024	This missense variant replaces serine with leucine at codon 206 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in breast and ovarian cancer case control studies in 0/60466 breast cancer cases and 4/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID BRIP1_000670) and in 0/3236 ovarian cancer cases and 1/3431 unaffected individuals (PMID: 26315354). This variant also has been reported in a colorectal and prostate cancer case-control studies in 1/12503 colorectal cancer cases and 0/23705 unaffected individuals (PMID: 33309985) and in 1/7636 prostate cancer cases and 0/12366 unaffected individuals (PMID: 31214711). This variant has been identified in 5/282696 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Uncertain significance, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Feb 07, 2022	Variant summary: BRIP1 c.617C>T (p.Ser206Leu) results in a non-conservative amino acid change located in the Helicase superfamily 1/2, ATP-binding domain (IPR014001) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 251312 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.617C>T has been reported in the literature in an individual affected with Breast Cancer (example, Weitzel_2019), and another individual affected with colorectal cancer (example, Fujita_2020), but was also found in controls (example, Ramus_2015, Dorling_2021). These report(s) do not provide unequivocal conclusions about association of the variant with Breast Cancer. At-least two co-occurrences with other pathogenic variant(s) have been observed at our laboratory (BARD1 c.1872delT , p.Leu625SerfsX7 ; BRCA1 c.(4986+1_4987-1)_(5074+1_5075-1)del [exon 16 del]), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (VUS, n=5, Likely Benign, n=1). Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 206 of the BRIP1 protein (p.Ser206Leu). This variant is present in population databases (rs565458815, gnomAD 0.003%). This missense change has been observed in individual(s) with breast and colorectal cancer (PMID: 31206626, 33309985). ClinVar contains an entry for this variant (Variation ID: 188324). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRIP1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
