This variant is denoted CDH1 c.1019C>T at the cDNA level, p.Thr340Met (T340M) at the protein level, and results in the change of a Threonine to a Methionine (ACG>ATG). This variant has not, to our knowledge, been published in the literature as a germline pathogenic or benign variant. CDH1 Thr340Met was not observed at a significant allele frequency in large population cohorts (Lek 2016). Since Threonine and Methionine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. CDH1 Thr340Met is located in cadherin 2 of the extracellular domain (Brooks-Wilson 2004, Figueiredo 2013). In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether CDH1 Thr340Met is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
