Invitae | RCV000546657 | SCV000622717 | uncertain significance | Ataxia-telangiectasia syndrome | 2018-02-27 | criteria provided, single submitter | clinical testing | This sequence change replaces phenylalanine with serine at codon 239 of the ATM protein (p.Phe239Ser). The phenylalanine residue is highly conserved and there is a large physicochemical difference between phenylalanine and serine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an ATM-related disease. ClinVar contains an entry for this variant (Variation ID: 187667). 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. In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
