Computational evidence

Protein change
AlphaMissense	0.117	likely benign
REVEL	0.321	indeterminate
SaProt	LLR -6.23	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no call.

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.
