REVEL	0.189	benign-leaning
SaProt	LLR -10.12	damaging
⇒ AlphaMissense and SaProt call this damaging; REVEL does 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.
