Protein change
AlphaMissense	0.0686	likely benign
REVEL	0.151	moderately benign-leaning
SaProt	LLR -5.30	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing

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

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.
