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.

This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 369 of the BRIP1 protein (p.Tyr369His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with breast cancer or colorectal cancer (PMID: 26921362, 28135145). ClinVar contains an entry for this variant (Variation ID: 140858). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on 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. -

The p.Y369H variant (also known as c.1105T>C), located in coding exon 7 of the BRIP1 gene, results from a T to C substitution at nucleotide position 1105. The tyrosine at codon 369 is replaced by histidine, an amino acid with similar properties. In one study, this alteration was detected in a heterozygous state in 1/16379 breast cancer cases and 1/8366 controls (Easton DF et al. J. Med. Genet., 2016 05;53:298-309). Additionally, this alteration was detected in a heterozygous state in 1/1058 unselected patients with colorectal cancer (Yurgelun MB et al. J. Clin. Oncol., 2017 Apr;35:1086-1095). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
