RCV003513464 | SCV004285940 | uncertain significance | Hereditary diffuse gastric adenocarcinoma | 2023-10-26 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 50 of the CDH1 protein (p.Arg50His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with pancreatic ductal adenocarcinoma (PMID: 35171259). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
| Ambry Genetics | RCV004604972 | SCV005095386 | likely benign | Hereditary cancer-predisposing syndrome | 2024-03-19 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
