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 c.2329G>A (p.Asp777Asn) missense variant has a frequency of 0.0001202 (34 of 282,830) in the gnomAD v2.1.1 cohort, with a maximum non-founder allele frequency of 0.0002400 (31 of 129,162) in the non-Finnish European subpopulation (http://gnomad.broadinstitute.org). This variant has been observed in >100 individuals without DGC, SRC tumours or LBC and whose families do not suggest HDGC (BS2; SCV000149760.14, SCV000261509.8, PMIDs: 29522266, 26534844, 26976419, 25142776, 24728327). In summary, the clinical significance of this variant is classified as Likely Benign based the ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): 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]

Variant summary: CDH1 c.2329G>A (p.Asp777Asn) results in a conservative amino acid change located in the Cadherin, cytoplasmic domain of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00012 in 277184 control chromosomes, predominantly at a frequency of 0.00024 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 11 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Breast and Ovarian Cancer phenotype (2.1e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.2329G>A has been reported in the literature in individuals affected with cancer including breast cancer, colorectal cancer and prostate cancer (Kraus_2015, Tung_2016, Hansford_2015, Zhang_2015, Jonsson_2002). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Eight clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (1x likely benign, 7x VUS). Based on the evidence outlined above, the variant was classified as likely benign. -

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. -
