Protein change
AlphaMissense	0.9999	likely pathogenic · top 5% in ANKRD17
REVEL	0.955	strongly pathogenic-leaning
SaProt	LLR -16.09	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
