Protein change
AlphaMissense	0.1473	likely benign
REVEL	0.2	benign-leaning
SaProt	LLR -12.50	damaging
⇒ SaProt calls this damaging; AlphaMissense and REVEL do not.

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.
