Criteria Specification Approval History
Criteria Specifications for this VCEP
Evidence submitted by expert panel
CDH1 VCEP
The c.2494G>A (p.Val832Met) variant has an allele frequency of 0.00175 (0.175%, 33/18,868 alleles) in the East Asian subpopulation of the gnomAD cohort (BS1). This variant has been observed in >10 individuals 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. ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS1, BS2.
