Protein change
AlphaMissense	0.1209	likely benign
REVEL	0.186	benign-leaning
SaProt	LLR -7.12	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Overall
CADD	25.7	PHRED · no single calibrated threshold — expert panels disagree

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

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.
