In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 28202063, 29295527, 15235021, 22850631, 32283892, 31159747) -
The CDH1 c.2387G>A (p.Arg796Gln) variant has been reported in the published literature in at least one reportedly healthy individual and affected individuals in large-scale breast cancer association studies (PMIDs: 30287823 (2018), 33471991 (2021), see also LOVD (https://databases.lovd.nl/shared/genes/CDH1)). Additionally, the variant was identified in an individual with unspecified cancer (PMID: 36436516 (2023)). The frequency of this variant in the general population, 0.00012 (3/24956 chromosomes in African/African American subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

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.2387G>A (p.Arg796Gln) results in a conservative amino acid change in the encoded protein sequence. Four of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.7e-05 in 403358 control chromosomes. The observed variant frequency is slightly higher than the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Diffuse Gastric Cancer phenotype (2.8e-05), suggesting that the variant is benign. A recent case-control study showed that this variant was not associated with breast cancer (Dorling_2021). The following publication has been ascertained in the context of this evaluation (PMID: 33471991). Nine submitters have submitted clinical-significance assessments for this variant to ClinVar after 2014; they reported the variant with conflicting assessments (Likely Benign n=3, VUS n=6). Based on the evidence outlined above, the variant was classified as likely benign. -
