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]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BP6: Variant 17-75941614-T-C is Benign according to our data. Variant chr17-75941614-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 325293.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00543 (827/152322) while in subpopulation AFR AF = 0.0163 (678/41574). AF 95% confidence interval is 0.0153. There are 5 homozygotes in GnomAd4. There are 375 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 5 AR,AD gene
