Protein change
AlphaMissense	0.1475	likely benign
REVEL	0.441	indeterminate
SaProt	LLR -6.89	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL is indeterminate.

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.
