Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2

This summary comes from the ClinGen Evidence Repository: The c.1273G>A (p.Val425Ile) variant results in a conservative missense change in the Cadherin 3 domain of CDH1. This variant was observed in 6 in 152,140 alleles in the gnomAD v3.1.2 population database. This variant was observed in a proband with oral clefting (PMID:27227907). However, this variants has also been observed in more than 10 individuals without GC, DGC, gastric SRC tumours or LBC and whose families do not suggest HDGC (BS2). In summary, this variant meets criteria to be classified as Likely Benign based on the 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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Feb 28, 2023	In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with endometrial or colorectal cancer and in an individual with oral clefting (Jori et al., 2015; Ittiwut et al., 2016; Do et al., 2022); This variant is associated with the following publications: (PMID: 24686850, 27227907, 26517685, 30287823, 32175104, 35098669, 31638429, 15235021, 22850631) -
Uncertain significance, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The CDH1 p.Val425Ile variant was not identified in the literature nor was it identified in the MutDB, Insight Colon Cancer Gene Variant Database, Zhejiang Colon Cancer Database, databases. The variant was identified in dbSNP (ID: rs570930882) as With Uncertain significance allele, ClinVar (classified as uncertain significance by GeneDx, Ambry Genetics, Invitae), Cosmic (classified as neutral (score 0.31)), databases. The variant was identified in control databases in 9 of 277228 chromosomes at a frequency of 0.000032 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Val425 residue is conserved in mammals but not in more distantly related organisms however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The variant is located with the Cadherin-like functional domain, the clinical significance of which cannot be determined. 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. -

Variant summary: CDH1 c.1273G>A (p.Val425Ile) results in a conservative amino acid change located in the Cadherin-like domain (IPR002126) of 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 5.1e-05 in 273966 control chromosomes (gnomAD and Momozawa_2018). The observed variant frequency is approximately 2.45 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Breast Cancer phenotype (2.1e-05), strongly suggesting that the variant is benign. c.1273G>A has been reported in the literature (e.g. Jori_2015, Kraemer_2019), but these reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. In addition, a large Japanese case-control study found the variant to be not associated with breast cancer risk (Momozawa_2018). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 33309985, 26517685, 31422574, 30287823, 36243179). Eight submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Multiple submitters reported the variant with conflicting assessments ranging from uncertain significance to benign, with the most common (four) being likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -
