| Ambry Genetics | RCV001011962 | SCV001172353 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-10-28 | criteria provided, single submitter | clinical testing | The p.G51R variant (also known as c.151G>A), located in coding exon 2 of the BRIP1 gene, results from a G to A substitution at nucleotide position 151. The glycine at codon 51 is replaced by arginine, an amino acid with dissimilar properties. 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. |
| Invitae | RCV001039314 | SCV001202840 | uncertain significance | Familial cancer of breast; Fanconi anemia complementation group J | 2019-12-19 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with BRIP1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 51 of the BRIP1 protein (p.Gly51Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. |
