Criteria Specifications for this VCEP
Evidence submitted by expert panel
CDH1 VCEP
The c.49-3C>A variant has been observed in at least three individuals without DGC, SRC tumours or LBC and whose families do not suggest HDGC (BS2_supporting; SCV000822625.1, SCV000570129.4, SCV000665064.2). In summary, the clinical significance of this variant is uncertain based on ACMP/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS2_supporting.
Met criteria codes
BS2_Supporting
This variant was observed in five individuals without DGC, SRC tumour or LBC and whose families do not suggest HDGC (Ambry, GeneDx, Invitae). However, this variant has also been found in two individuals with notable personal and family history: one individual with breast cancer and a second-degree relative with gastric cancer, both in 70s (Invitae), and one individual with IDC and ILC in 50s and first-degree relative with gastric cancer in 70s (GeneDx).
