Protein change
AlphaMissense	0.1286	likely benign
REVEL	0.058	moderately benign-leaning
SaProt	LLR -5.72	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.
