Is AOX1 p.Ala4Pro (c.10G>C) pathogenic?

AOX1 p.Ala4Pro (c.10G>C) is classified Uncertain significance in AOX1 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-03-28). AlphaMissense: likely benign (0.0858); Ultra-rare (popmax 0.0225%, mid).

How common is AOX1 p.Ala4Pro (c.10G>C) in the general population?

AOX1 p.Ala4Pro (c.10G>C) is ultra-rare (popmax 0.0225%, mid) (gnomAD).

What do computational predictors say about AOX1 p.Ala4Pro (c.10G>C)?

AlphaMissense predicts likely benign (score 0.0858) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0858	likely benign
REVEL	0.025	moderately benign-leaning
SaProt	LLR -2.01	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.
