Protein change
AlphaMissense	0.9912	likely pathogenic
REVEL	0.873	moderately pathogenic-leaning
SaProt	LLR -14.68	damaging
⇒ AlphaMissense, REVEL and SaProt all call this damaging.

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

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

Population frequency

Grpmax group 8.68e-05% European (non-Finnish) · 1/1,152,344 alleles

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.
