Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV002271418	SCV000698383	likely benign	not specified	2023-10-02	criteria provided, single submitter	clinical testing	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.
