Invitae RCV001057625 SCV001222128 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces valine with isoleucine at codon 891 of the BRIP1 protein (p.Val891Ile). The valine residue is moderately conserved and there is a small physicochemical difference between valine and isoleucine. This variant is present in population databases (rs754224663, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. 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 isoleucine 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.
Color Diagnostics, LLC DBA Color Health RCV001806004 SCV002052053 uncertain significance Hereditary cancer-predisposing syndrome 2021-03-15 criteria provided, single submitter clinical testing This missense variant replaces valine with isoleucine at codon 891 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 reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 1/251244 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.
