RCV000706304 | SCV000835346 | uncertain significance | Ataxia-telangiectasia syndrome | 2018-07-02 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with ATM-related disease. 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with glycine at codon 1304 of the ATM protein (p.Arg1304Gly). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and glycine. |
| Ambry Genetics | RCV003165921 | SCV003858403 | likely benign | Hereditary cancer-predisposing syndrome | 2023-01-18 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
