Genes affected

CDH1 (HGNC:1748): (cadherin 1) This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function of this gene is thought to contribute to cancer progression by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. This gene is present in a gene cluster with other members of the cadherin family on chromosome 16. [provided by RefSeq, Nov 2015]

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 598 of the CDH1 protein (p.Arg598Gln). This variant is present in population databases (rs780759537, gnomAD 0.01%). This missense change has been observed in individual(s) with breast cancer (PMID: 25186627, 35534704). ClinVar contains an entry for this variant (Variation ID: 188221). 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. -

Collection Method: 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces arginine with glutamine at codon 598 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been observed in a tumor sample from an individual with diffuse gastric cancer (PMID: 9744472, 10094558), in an individual affected with breast cancer (PMID 25186627) and in an unaffected control individual (PMID: 30287823). This variant has been identified in 7/282886 chromosomes 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. -

Variant summary: CDH1 c.1793G>A (p.Arg598Gln) results in a conservative amino acid change located in the Cadherin-like (IPR002126) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.3e-05 in 352614 control chromosomes (gnomAD, Momozawa_2018, Akcay_2021, Okawa_2023). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1793G>A has been reported in the literature in individuals affected with breast cancer or endometrial cancer without strong evidence of causality (Tung_2015, Tian_2019, Dorling_2021, de Oliveira_2022). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Diffuse Gastric Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 32658311, 30287823, 33471991, 36243179, 35534704, 31054147, 25186627). Five submitters have cited clinical-significance assessments for this variant to ClinVar after 2014, and classified it as uncertain significance (n=4) or likely benign (n=1). Based on the evidence outlined above, the variant was classified as uncertain significance. -
