Submissions by phenotype
Hereditary diffuse gastric adenocarcinoma Uncertain:1
This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 620 of the CDH1 protein (p.Pro620Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CDH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 185044). 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. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.P620T variant (also known as c.1858C>A), located in coding exon 12 of the CDH1 gene, results from a C to A substitution at nucleotide position 1858. The proline at codon 620 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
