Description

This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 2140 of the ATM protein (p.Phe2140Leu). This variant is present in population databases (rs587780635, gnomAD 0.009%). This missense change has been observed in individual(s) with pancreatic ductal adenocarcinoma, breast and/or ovarian cancer (PMID: 29470806, 33646313, 35171259). ClinVar contains an entry for this variant (Variation ID: 135771). 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. 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.
