Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BS2BS1

This summary comes from the ClinGen Evidence Repository: The c.188G>A (p.Arg63Gln) variant has an allele frequency of 0.00109 (0.11%, 6/5486 alleles) in the “Other” subpopulation of the gnomAD cohort (BS1). This variant has also been observed in >10 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, this variant meets criteria to be classified as benign.

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 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. -

Collection Method: clinical testing

The CDH1 p.Arg63Gln variant was not identified in the literature nor was it identified in the Cosmic, MutDB, or in the Zhejiang University database. The variant was identified in dbSNP (ID: rs587780117) as "With Uncertain significance allele", and in ClinVar (classified as uncertain significance by GeneDx, Ambry Geneitcs, Invitae). The variant was identified in control databases in 17 of 246200 chromosomes at a frequency of 0.00007 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 15304 chromosomes (freq: 0.00007), Other in 6 of 5486 chromosomes (freq: 0.001), European in 3 of 111650 chromosomes (freq: 0.00003), and South Asian in 7 of 30782 chromosomes (freq: 0.0002); it was not observed in the Latino, Ashkenazi Jewish, East Asian, and Finnish populations. The p.Arg63 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, 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) 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. This variant is classified as a variant of uncertain significance. -
