⚑ Evidence disagreements 54

Variants where the independent computational evidence doesn't line up with the clinical picture — a QC signal for a second look, not a reclassification.

Predictors vs ClinVar 1

ClinVar calls these pathogenic, but the computational predictors lean tolerated — the highest-value review flag.

Predictors agree, ClinVar conflicts 1

ClinVar submitters conflict, but the independent predictors unanimously agree — a QC review flag, not a reclassification.

Predicted LoF vs a conflicting call 1

ClinVar submitters conflict, and it's a predicted loss-of-function change in a gene where LoF causes disease — flagged for review, not resolved (verify NMD-escape for C-terminal truncations). Non-missense.

Predictors lean, ClinVar uncertain 40

ClinVar classifies these uncertain (VUS), but the independent predictors unanimously lean one way — a triage signal for review, not a reclassification.
