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]

This alteration is classified as 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. -

Variant summary: CDH1 c.2104G>A (p.Glu702Lys) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00021 in 282492 control chromosomes, predominantly at a frequency of 0.0016 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 57 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Diffuse Gastric Cancer phenotype (2.8e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. In addition, this variant was found in nine healthy older women in a reputed germline gnomic database (FLOSSIES). The variant, c.2104G>A has been reported in the literature in individuals affected with Hereditary Diffuse Gastric Cancer (Yurgelun_2015/2017, Ghazani_2017). 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. Nine ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance (2x), likely benign (5x) and benign (2x). Additionally, one expert panel (ClinGen CDH1 Variant Curation Expert Panel) cites this variant as benign. Based on the evidence outlined above, the variant was classified as benign. -
