Protein change
AlphaMissense	0.1909	likely benign
REVEL	0.043	moderately benign-leaning
SaProt	LLR -8.10	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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

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