Protein change
AlphaMissense	0.7517	likely pathogenic
REVEL	0.45	indeterminate
SaProt	LLR -14.35	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL makes no call.

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.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
