Hereditary cancer-predisposing syndrome Uncertain:2
The p.Q641R variant (also known as c.1922A>G), located in coding exon 12 of the CDH1 gene, results from an A to G substitution at nucleotide position 1922. The glutamine at codon 641 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is poorly 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. -
This missense variant replaces glutamine with arginine at codon 641 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with CDH1-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Hereditary diffuse gastric adenocarcinoma Uncertain:1
This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 641 of the CDH1 protein (p.Gln641Arg). 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: 232981). 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 tolerated. 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. -
not provided Uncertain:1
This variant is denoted CDH1 c.1922A>G at the cDNA level, p.Gln641Arg (Q641R) at the protein level, and results in the change of a Glutamine to an Arginine (CAG>CGG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. CDH1 Gln641Arg was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Glutamine and Arginine differ in some properties, this is considered a semi-conservative amino acid substitution. CDH1 Gln641Arg occurs at a position that is not conserved and is located within the cadherin 5 domain (UniProt). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available information, it is unclear whether CDH1 Gln641Arg is pathogenic or benign. We consider it to be a variant of uncertain significance. -
