Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

This summary comes from the ClinGen Evidence Repository: The NM_004360.5(CDH1):c.394G>A (p.Val132Ile) variant has been observed in >10 individuals without a diagnosis of diffuse gastric cancer, signet ring tumor or lobular breast cancer and whose family histories do not suggest HDGC (BS2; internal laboratory contributors). In summary, the clinical significance of this variant is classified as likely benign based on BS2 alone. ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel: BS2.

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 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. -

CDH1-related disorder Uncertain:1
May 14, 2024
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The CDH1 c.394G>A variant is predicted to result in the amino acid substitution p.Val132Ile. This variant has been identified in an individual with breast cancer (Supplementary data, Tung et al. 2015. PubMed ID: 25186627), as well as in an individual with colorectal cancer (Table A4, Yurgelun et al. 2017. PubMed ID: 28135145). This variant is reported in 0.048% of alleles in individuals of African descent in gnomAD and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/142546/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Women's Health and Genetics/Laboratory Corporation of America, LabCorp
Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: CDH1 c.394G>A (p.Val132Ile) 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 5.3e-05 in 282708 control chromosomes, predominantly at a frequency of 0.00048 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 23 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (2.1e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. c.394G>A has been reported in the literature in sequencing studies of individuals affected with breast cancer and colorectal cancer (example, Tung_2015, Yurgelun_2017). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (benign, n=1; likely benign, n=3; VUS, n=3) with an emerging consensus towards a benign outcome since its previous evaluation. Based on the evidence outlined above, the variant was re-classified as benign. -
