Protein change
AlphaMissense	0.1563	likely benign
REVEL	0.902	moderately pathogenic-leaning
SaProt	LLR -10.59	damaging
⇒ REVEL and SaProt call this damaging; AlphaMissense 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.
