SaProt	LLR -4.16	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.
