Protein change
AlphaMissense	0.645	likely pathogenic
REVEL	0.294	indeterminate
SaProt	LLR -13.96	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL is indeterminate.

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

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