Protein change
AlphaMissense	0.1293	likely benign
REVEL	0.088	moderately benign-leaning
SaProt	LLR -8.36	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Overall
CADD	16.58	PHRED · no single calibrated threshold — expert panels disagree

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.
