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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Dec 11, 2023	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 591 of the ACOX1 protein (p.Arg591His). This variant is present in population databases (rs369561903, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with ACOX1-related conditions. ClinVar contains an entry for this variant (Variation ID: 547859). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The c.1772G>A (p.R591H) alteration is located in exon 13 (coding exon 13) of the ACOX1 gene. This alteration results from a G to A substitution at nucleotide position 1772, causing the arginine (R) at amino acid position 591 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
