This summary comes from the ClinGen Evidence Repository: The c.2399G>A (p.Arg800His) variant has an allele frequency of 0.00003 (0.003%, 1/30,614 alleles) in the South Asian gnomAD subpopulation (http://gnomad.broadinstitute.org). The variant has been seen in >10 individuals without DCG, SRC tumors, or LBC and whose families do notsuggest HDGC (BS2; PMID:26072394, SCV000186429.5, SCV000210876.13, SCV000254822.4). The variant has been identified in the homozygous state in an individual without personal and family history of DGC, LBC, or SRC tumors (BP2_Strong; SCV000186429.5). In summary, this variant meets criteria to be classified as benign based on the ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS2, BP2_Strong.

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

This missense variant replaces arginine with histidine at codon 800 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with intestinal-type gastric cancer (PMID: 26072394). This variant has been identified in 4/251258 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. -

Ambry Genetics
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.2399G>A (p.Arg800His) variant has an allele frequency of 0.00003 (0.003%, 1/30,614 alleles) in the South Asian gnomAD subpopulation (http://gnomad.broadinstitute.org). The variant has been seen in >10 individuals without DCG, SRC tumors, or LBC and whose families do not suggest HDGC (BS2; PMID: 26072394, SCV000186429.5, SCV000210876.13, SCV000254822.4). The variant has been identified in the homozygous state in an individual without personal and family history of DGC, LBC, or SRC tumors (BP2_Strong; SCV000186429.5). In summary, this variant meets criteria to be classified as benign based on the ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS2, BP2_Strong. -

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

This variant is denoted CDH1 c.2399G>A at the cDNA level, p.Arg800His (R800H) at the protein level, and results in the change of an Arginine to a Histidine (CGC>CAC). This variant has been observed in at least one individual with gastric cancer (van der Post 2015). CDH1 Arg800His was not observed at a significant allele frequency in the NHLBI Exome Sequencing Project. Since Arginine and Histidine share similar properties, this is considered a conservative amino acid substitution. CDH1 Arg800His occurs at a position that is conserved across species and is located in the cytoplasmic domain (Brooks-Wilson 2004, Figueiredo 2013). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available information, it is unclear whether CDH1 Arg800His is pathogenic or benign. We consider it to be a variant of uncertain significance. -
