Ambry Genetics | RCV001014661 | SCV001175396 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-07-20 | criteria provided, single submitter | clinical testing | The p.T722I variant (also known as c.2165C>T), located in coding exon 14 of the BRIP1 gene, results from a C to T substitution at nucleotide position 2165. The threonine at codon 722 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV001216078 | SCV001387853 | uncertain significance | Familial cancer of breast; Fanconi anemia complementation group J | 2021-09-02 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with isoleucine at codon 722 of the BRIP1 protein (p.Thr722Ile). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and isoleucine. This variant is not present in population databases (ExAC no frequency). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |
