Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. BS2PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The c.731A>G (p.Asp244Gly) variant results in a non-conservative amino acid substitution in the Cadherin-1 domain. This variant has a frequency of 6.57x10-6 (1 in 152,170 alleles) in gnomAD (PM2_supporting) and has been reported in one family meeting IGCLC criteria for HDGC (PMID:10319582). However, this variant has been observed in more than 30 families without DGC, LBC or SRC tumours and whose families do not suggest HDGC (BS2; unpublished). Functional studies of the p.Asp244Gly variant suggest that this variant may affect the subcellular localization of E-cadherin and regulation of cell adhesion (PMID:27582386, 28301459). In summary, this variant is classified as likely benign based on ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel: BS2, PM2_supporting.

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]

Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The frequency of this variant in the general population, 0.0000066 (1/152170 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in an individual with gastric cancer (PMIDs: 10319582 (1999)). Functional studies state that the variant results in loss of cytoplasmic membrane localization (PMID: 28301459 (2017)), as well as inhibits basic E-cadherin adhesion function (PMID: 27582386 (2016)), and is considered destabilizing (PMID: 22470475 (2012)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is denoted CDH1 c.731A>G at the cDNA level, p.Asp244Gly (D244G) at the protein level, and results in the change of an Aspartic Acid to a Glycine (GAT>GGT). This variant was observed in at least one individual with a personal and family history of gastric cancer (Yoon 1999). Functional studies suggest that this variant may result in decreased adhesion, increased migration, and loss of E-cadherin cytoplasmic membrane localization compared to wild type (Petrova 2016, Ghoumid 2017). CDH1 Asp244Gly was not observed in large population cohorts (Lek 2016). This variant is located in the Cadherin 1 domain (Brooks-Wilson 2004, Figueiredo 2013, UniProt). In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether CDH1 Asp244Gly is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -

Significance:Likely benign
Review Status:criteria provided, single submitter
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. -

The c.731A>G (p.Asp244Gly) variant results in a non-conservative amino acid substitution in the Cadherin-1 domain.
