Protein change
AlphaMissense	0.9889	likely pathogenic · top 6% in RIN2
REVEL	0.548	indeterminate
SaProt	LLR -12.24	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.
