Genes affected
ACOX1 (HGNC:119): (acyl-CoA oxidase 1) The protein encoded by this gene is the first enzyme of the fatty acid beta-oxidation pathway, which catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. It donates electrons directly to molecular oxygen, thereby producing hydrogen peroxide. Defects in this gene result in pseudoneonatal adrenoleukodystrophy, a disease that is characterized by accumulation of very long chain fatty acids. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitterclinical testingGeneDxNov 30, 2017The R148X nonsense variant in the ACOX1 gene has been reported previously in association with peroxisomal acyl-CoA oxidase deficiency in an individual who was homozygous for R148X (Ferdinandusse et al., 2007). The R148X variant is not observed in large population cohorts (Lek et al., 2016). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. In summary, we interpret R148X to be a pathogenic variant. -
