Submissions by phenotype
Ataxia-telangiectasia syndrome Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1998 of the ATM protein (p.Gly1998Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 453608). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.G1998V variant (also known as c.5993G>T), located in coding exon 39 of the ATM gene, results from a G to T substitution at nucleotide position 5993. The glycine at codon 1998 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
