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	Nov 08, 2021	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 27, 2023	The p.D753G variant (also known as c.2258A>G) is located in coding exon 15 of the BRIP1 gene. The aspartic acid at codon 753 is replaced by glycine, an amino acid with similar properties. This change occurs in the first base pair of coding exon 15. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Jan 11, 2021	This missense variant replaces aspartic acid with glycine at codon 753 of the BRIP1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with prostate cancer and in unaffected individuals in a case-control study (PMID: 31214711). This variant has been identified in 3/251200 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. -

This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 753 of the BRIP1 protein (p.Asp753Gly). This variant is present in population databases (rs745578572, gnomAD 0.02%). This missense change has been observed in individual(s) with prostate cancer (PMID: 31214711). ClinVar contains an entry for this variant (Variation ID: 184968). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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. -
