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	Ambry Genetics	Jun 16, 2022	The p.A406S variant (also known as c.1216G>T), located in coding exon 8 of the BRIP1 gene, results from a G to T substitution at nucleotide position 1216. The alanine at codon 406 is replaced by serine, an amino acid with similar properties. In one study, this alteration was detected in a heterozygous state in 1/13,213 breast cancer cases and 0/5,242 controls from the United Kingdom (Easton DF et al. J. Med. Genet., 2016 05;53:298-309). This amino acid position is well 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. -

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 406 of the BRIP1 protein (p.Ala406Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with breast cancer (PMID: 26921362). ClinVar contains an entry for this variant (Variation ID: 407821). 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 with a negative predictive value of 80%. 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. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with breast cancer and absent in controls (Easton et al., 2016; Dorling et al., 2021); This variant is associated with the following publications: (PMID: 33471991, 26921362) -

The BRIP1 c.1216G>T (p.Ala406Ser) missense change is absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant has been reported in an individual with breast cancer (PMID: 26921362). To our knowledge, this variant has not been reported in individuals with Fanconi anemia. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -
