⚑ Evidence disagreements 255

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 2

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

Predictors agree, ClinVar conflicts 32

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

Predictors lean, ClinVar uncertain 127

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

Predictors split 94

The independent predictors disagree with each other — read with care.
