Protein change
AlphaMissense	0.9688	likely pathogenic · top 9% in IPO8
REVEL	0.248	benign-leaning
SaProt	LLR -12.81	damaging
⇒ AlphaMissense and SaProt call this damaging; REVEL does not.

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Population frequency

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.
