Criteria Specification Approval History
Criteria Specifications for this VCEP
Evidence submitted by expert panel
CDH1 VCEP
The c.2440-2A>G variant is a canonical splice variant predicted to result in a truncated or absent protein (PVS1_Strong, PM5_Supporting). This variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). There is also an RNA assay demonstrating abnormal splicing (PS3_Moderate; SCV000700319.2). In summary, this variant meets criteria to be classified as likely pathogenic based on the ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): PVS1_strong, PM2_Supporting, PS3_Moderate, PM5_Supporting.
Met criteria codes
PVS1_Strong
As per CDH1 ClinGen guidelines, PVS1_strong is invoked for canonical splice variants. This site is invariant in all transcripts. Predicted exon 16 skipping (last exon), leading to loss of the last 69 aa residues, p.(Asn814_Asp882del), which accounts for ~7.8% of protein. Most 3' pathogenic variant is c.2506G>T p.(Glu836*). No other variants at this position are recorded in ClinVar.
PM5_Supporting
Apply PM5_Supporting to the variant with the alteration at canonical splicing site.
PM2_Supporting
Not observed in population databases.
PS3_Supporting
SCV000700319.2 Ambry - RNA studies show abnormal splicing resulting in out-of-frame transcript. To avoid overweighting the evidence toward pathogenicity, VCEP recommended downgrading PS3 to PS3_Moderate.
