Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_000051.4(ATM):c.6269A>C(p.Asp2090Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D2090N) has been classified as Uncertain significance.

Ataxia-telangiectasia syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 27, 2021 | This sequence change replaces aspartic acid with alanine at codon 2090 of the ATM protein (p.Asp2090Ala). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and alanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with ATM-related conditions. 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. 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. - |
