Protein change
AlphaMissense	0.3595	ambiguous
REVEL	0.089	moderately benign-leaning
SaProt	LLR -4.78	tolerated
⇒ REVEL and SaProt both call this tolerated; AlphaMissense is indeterminate.

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.
