Genes affected

ABCD1 (HGNC:61): (ATP binding cassette subfamily D member 1) The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the ALD subfamily, which is involved in peroxisomal import of fatty acids and/or fatty acyl-CoAs in the organelle. All known peroxisomal ABC transporters are half transporters which require a partner half transporter molecule to form a functional homodimeric or heterodimeric transporter. This peroxisomal membrane protein is likely involved in the peroxisomal transport or catabolism of very long chain fatty acids. Defects in this gene have been identified as the underlying cause of adrenoleukodystrophy, an X-chromosome recessively inherited demyelinating disorder of the nervous system.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg85Glyfs*18) in the ABCD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ABCD1 are known to be pathogenic (PMID: 11748843). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ABCD1-related conditions. For these reasons, this variant has been classified as Pathogenic.

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The variant is not observed in the gnomAD v2.1.1 dataset. The variant is predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline.
