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]

The CDH1 c.1988A>G (p.Tyr663Cys) missense change has a maximum subpopulation frequency of 0.0040% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). To our knowledge, this variant has not been reported in the literature in individuals with diffuse gastric and lobular breast cancer syndrome. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Variant summary: CDH1 c.1988A>G (p.Tyr663Cys) results in a non-conservative amino acid change located in the Cadherin-like domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251478 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1988A>G has been reported in the literature in individuals affected with Pancreatic cancer or Prostate cancer. 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. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Based on the evidence outlined above, the variant was classified as uncertain significance. -

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

The frequency of this variant in the general population, 0.000031 (4/129178 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in individuals with breast cancer (PMID: 29522266 (2018)), prostate cancer (PMID: 29522266 (2018)), and pancreatic cancer (PMID: 28767289 (2017)). 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. -

Color Diagnostics, LLC DBA Color Health
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces tyrosine with cysteine at codon 663 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast and/or ovarian cancer, prostate cancer and pancreatic cancer (PMID: 28767289, 29368341, 29522266). This variant has been identified in 5/282856 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. -

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. -

Collection Method: clinical testing

The CDH1 p.Tyr663Cys variant was not identified in the literature nor was it identified in the Cosmic, MutDB, or Zhejiang University database. The variant was identified in dbSNP (ID: rs372182377) as "With Uncertain significance allele", and in ClinVar (classified as uncertain significance by Invitae, GeneDx, Ambry Genetics and two other submitters). The variant was identified in 5 of 277208 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 24028 chromosomes (freq: 0.00004), European in 4 of 126710 chromosomes (freq: 0.00003), but not in the Other, Latino, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Tyr663 residue is conserved across mammals and other organisms, and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
