RCV001340917 | SCV001534751 | uncertain significance | Ataxia-telangiectasia syndrome | 2022-10-07 | 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 1037724). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 855 of the ATM protein (p.Met855Ile). |
| Ambry Genetics | RCV003169619 | SCV003866521 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-12-07 | criteria provided, single submitter | clinical testing | The p.M855I variant (also known as c.2565G>C), located in coding exon 16 of the ATM gene, results from a G to C substitution at nucleotide position 2565. The methionine at codon 855 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is not well 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. |
