Protein change
AlphaMissense	0.1488	likely benign
REVEL	0.101	moderately benign-leaning
SaProt	LLR -11.54	damaging
⇒ SaProt calls this damaging; AlphaMissense and REVEL do not.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM R186W vs ClinVar R265W) — verify the residue.

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.
