Protein change
AlphaMissense	0.2042	likely benign
REVEL	0.343	indeterminate
SaProt	LLR -4.77	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.

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.
