Protein change
AlphaMissense	0.8742	likely pathogenic
REVEL	0.786	moderately pathogenic-leaning
SaProt	LLR -4.32	tolerated
⇒ AlphaMissense and REVEL call this damaging; SaProt 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.
