⚑ Evidence disagreements 500

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 agree, ClinVar conflicts 28

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

Predictors lean, ClinVar uncertain 361

ClinVar classifies these uncertain (VUS), but the independent predictors unanimously lean one way — a triage signal for review, not a reclassification. · showing the 150 best-reviewed of 361

Predictors split 111

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