Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BS2BP2_StrongBS1

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.1568A>G (p.Tyr523Cys) variant in the CDH1 gene is 0.15% for Latino/Admixed American chromosomes in gnomAD (95% CI of 23/15282), which meets the allele frequency threshold defined by the ClinGen CDH1 Variant Curation Expert Panel for considering strong evidence against pathogenicity for autosomal dominant hereditary diffuse gastric cancer variants (BS1). This 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). This variant was observed in the homozygous state in 9 individuals without personal and/or family history of DGC, LBC, or SRC tumors (BP2_strong; internal laboratory contributors). In summary, the clinical significance of this variant is classified as benign. ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel: BS1, 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

The CDH1 c.1568A>G (p.Tyr523Cys) missense change has a maximum subpopulation frequency of 0.011% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). This variant is located adjacent to the acceptor splice site of intron 10, however it is not predicted to affect splicing. Canonical splice site variants affecting this acceptor site are predicted to result in an in-frame insertion with a potential rescue transcript (PMID: 36600593). This variant has been identified in BRCA1/2-negative breast cancer patients, however it is unknown if these individuals had lobular breast cancer (PMID: 29522266, 31780696). 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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered likely benign. Homozygosity has been confirmed in one or more individuals. As homozygosity for pathogenic variants in this gene is generally assumed to result in embryonic lethality, this variant is unlikely to be pathogenic. -

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. -

Variant summary: CDH1 c.1568A>G (p.Tyr523Cys) results in a non-conservative amino acid change located in the Cadherin-like domian (IPR002126) 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 0.00017 in 151000 control chromosomes (gnomAD v3.1.2), predominantly at a frequency of 0.0015 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 53 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 Latino origin. To our knowledge, no experimental evidence demonstrating its impact on protein function have been reported. Eight ClinVar submitters have assessed the variant since 2014: five classified the variant as uncertain significance, two as likely benign, and one as benign. Based on the evidence outlined above, the variant was classified as likely benign. -

The filtering allele frequency of the c.1568A>G (p.Tyr523Cys) variant in the CDH1 gene is 0.15% for Latino/Admixed American chromosomes in gnomAD (95% CI of 23/15282), which meets the allele frequency threshold defined by the ClinGen CDH1 Variant Curation Expert Panel for considering strong evidence against pathogenicity for autosomal dominant hereditary diffuse gastric cancer variants (BS1). This 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). This variant was observed in the homozygous state in 9 individuals without personal and/or family history of DGC, LBC, or SRC tumors (BP2_strong; internal laboratory contributors). In summary, the clinical significance of this variant is classified as benign. ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel: BS1, BS2, BP2_strong.
