⚑ Evidence disagreements 77

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.

Predictors lean, ClinVar uncertain 56

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