The recorded framework is ClinGen CDH1 VCEP v3.1. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
NM_004360.5:c.48+6_48+7delinsTT is absent from gnomAD v2.1, v4.1, and gnomAD-Canada v1.0, meeting the CDH1 VCEP PM2_Supporting criterion (≤1 in 100,000 alleles). The VCEP specifies PM2 at supporting strength with the requirement that coverage of CDH1 in the population database be at least 30x.
No benign criterion marked as applied in the recorded assessment.
ClinGen CDH1 Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines Version 3.1 v3.1 lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting; combination = 1 supporting, which maps to VUS.

NM_004360.5:c.48+6_48+7delinsTT is an intronic variant affecting positions +6 and +7 of CDH1 intron 1, outside the canonical splice consensus sequence.
This variant is absent from gnomAD v2.1 and v4.1 population databases, meeting the CDH1 VCEP PM2_Supporting criterion (≤1 in 100,000 alleles).
SpliceAI predicts no significant splice impact (max delta score 0.06). However, only SpliceAI data is available among the seven splicing predictors specified by the CDH1 VCEP, which is insufficient to meet PP3 or BP4 thresholds requiring at least three concordant predictors.
No RNA functional studies, de novo occurrence data, case-control data, co-segregation data, or family studies meeting HDGC criteria were identified for this variant.
This variant has been reported in ClinVar as Likely benign (VariationID 136068) with a 1-star review status (criteria provided, single submitter). The ClinVar-associated publications are clinical practice guidelines and policy statements that do not provide variant-specific evidence.
With only PM2_Supporting met and no other pathogenic or benign criteria satisfied, this variant is classified as a Variant of Uncertain Significance under the CDH1 VCEP framework (v3.1). The ClinVar Likely benign classification has low evidentiary weight (1-star) and cannot independently drive a benign classification.
