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: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is considered benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. 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. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -

Variant summary: CDH1 c.1888C>G (p.Leu630Val) results in a conservative amino acid change located in the Cadherin of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 183.84 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 East Asian origin. The variant allele was found at a frequency of 0.00037 in 277212 control chromosomes, predominantly at a frequency of 0.0052 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 250 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 East Asian origin. c.1888C>G has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer. These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. Co-occurrences with other pathogenic variant(s) have been reported (BRIP1 del exons 4-5), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -

The c.1888C>G (p.Leu630Val) variant has an allele frequency of 0.00519 (0.52%, 98/18,866 alleles) in the East Asian subpopulation of the gnomAD cohort (BA1).

Significance: Likely benign
Review Status: no assertion criteria provided
Collection Method: clinical testing

The CDH1 p.Leu630Val variant was identified in 3 of 512 proband chromosomes (frequency: 0.006) from individuals or families with gastric cancer or oral cleft and was present in 2 of 480 control chromosomes (frequency: 0.004) from healthy individuals (Chen 2013, Huang 2017). The variant was also identified in dbSNP (ID: rs2276331) as "With other allele", ClinVar (classified as benign by ClinGen CDH1 Variant Curation Expert Panel, Ambry Genetics, Invitae; and as likely benign by GeneDx, Quest Diagnostics, Color Genomics). The variant was identified in control databases in 102 of 277212 chromosomes at a frequency of 0.0004 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 3 of 6464 chromosomes (freq: 0.0005), East Asian in 98 of 18866 chromosomes (freq: 0.005), and South Asian in 1 of 30782 chromosomes (freq: 0.00003); it was not observed in the African, Latino, European Non-Finnish, Ashkenazi Jewish, or Finnish, populations. Two studies assessed the p.Leu630Val variant using in silico analysis and consider it to be “probably damaging”, however it was recommended that in vitro studies would be necessary to confirm the findings (Chen 2013, Santhiya 2013). The p.Leu630 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
