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	Labcorp Genetics (formerly Invitae), Labcorp	Dec 26, 2023	This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1060 of the BRIP1 protein (p.Val1060Ile). This variant is present in population databases (rs149016505, gnomAD 0.006%). This missense change has been observed in individual(s) with breast cancer (PMID: 26921362). ClinVar contains an entry for this variant (Variation ID: 461140). 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 tolerated. 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. -

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	May 02, 2023	The p.V1060I variant (also known as c.3178G>A), located in coding exon 19 of the BRIP1 gene, results from a G to A substitution at nucleotide position 3178. The valine at codon 1060 is replaced by isoleucine, an amino acid with highly similar properties. This variant has been reported in patients with breast cancer (Tung N et al. Cancer. 2015 Jan;121:25-33; Easton DF et al. J. Med. Genet. 2016 05;53:298-309). This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. 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 20, 2021	This missense variant replaces valine with isoleucine at codon 1060 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. This variant has been reported in individuals affected with breast cancer (PMID: 25186627, 26921362). This variant has also been identified in 2/251440 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. -
