Protein change
AlphaMissense	0.7791	likely pathogenic · top 8% in PEX26
REVEL	0.928	moderately pathogenic-leaning
SaProt	LLR -10.60	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.

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.
