AOX1
Chr 2aldehyde oxidase 1
Also known as: AO, AOH1
Aldehyde oxidase is a metabolic enzyme that oxidizes aromatic compounds and aldehydes, playing a key role in xenobiotic and drug metabolism while also participating in reactive oxygen species homeostasis. Mutations cause autosomal recessive cutis laxa with severe pulmonary, gastrointestinal, and genitourinary anomalies, typically presenting in the neonatal period. This gene shows very low constraint against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is gain-of-function.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
