Labcorp Genetics (formerly Invitae), Labcorp RCV001322142 SCV001512999 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2021-11-05 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 983 of the BRIP1 protein (p.Ile983Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1022256). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.

Ambry Genetics RCV001525964 SCV002752494 uncertain significance Hereditary cancer-predisposing syndrome 2023-03-30 criteria provided, single submitter clinical testing The p.I983T variant (also known as c.2948T>C), located in coding exon 19 of the BRIP1 gene, results from a T to C substitution at nucleotide position 2948. The isoleucine at codon 983 is replaced by threonine, an amino acid with similar properties. 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.
