Protein change
AlphaMissense	0.9568	likely pathogenic · top 6% in INF2
REVEL	0.675	pathogenic-leaning
SaProt	LLR -13.61	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.
