Protein change
AlphaMissense	0.9984	likely pathogenic
REVEL	0.916	moderately pathogenic-leaning
SaProt	LLR -10.58	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM R187K vs ClinVar R157K) — verify the residue.
