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]

Submissions by phenotype

Hereditary diffuse gastric adenocarcinoma

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jan 05, 2024	This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 524 of the CDH1 protein (p.Arg524Gly). This variant is present in population databases (rs373605261, gnomAD 0.007%). 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: 184348). 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. -

Uncertain significance, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Mar 06, 2023	This variant is classified as a variant of uncertain significance as there is insufficient evidence to determine its impact on protein function and/or cancer risk. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 31, 2023	The p.R524G variant (also known as c.1570C>G), located in coding exon 11 of the CDH1 gene, results from a C to G substitution at nucleotide position 1570. The arginine at codon 524 is replaced by glycine, an amino acid with dissimilar properties. This variant was reported in 2/60,466 breast cancer cases and in 0/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Oct 31, 2023	This missense variant replaces arginine with glycine at codon 524 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. In a large breast cancer case-control study, this variant has been observed in 2/60466 cases and 0/53461 unaffected controls (PMID: 33471991). This variant has been identified in 2/251482 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. -
