RCV000479921 | SCV000570216 | uncertain significance | not provided | 2016-05-03 | criteria provided, single submitter | clinical testing | This variant is denoted CDH1 c.1726A>G at the cDNA level, p.Thr576Ala (T576A) at the protein level, and results in the change of a Threonine to an Alanine (ACT>GCT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. CDH1 Thr576Ala was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Threonine and Alanine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. CDH1 Thr576Ala occurs at a position that is conserved across species and is located in the Cadherin 4 domain (UniProt). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether CDH1 Thr576Ala is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. |

RCV003624415 | SCV004423801 | uncertain significance | Hereditary diffuse gastric adenocarcinoma | 2023-01-20 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). ClinVar contains an entry for this variant (Variation ID: 421116). This variant has not been reported in the literature in individuals affected with CDH1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 576 of the CDH1 protein (p.Thr576Ala). |
