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.

This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 389 of the ABCD1 protein (p.Arg389Gly). This variant is not present in population databases (gnomAD no frequency). ClinVar contains an entry for this variant (Variation ID: 11296). This missense change has been observed in individual(s) with adrenomyeloneuropathy (PMID: 8566952, 15811009, 22479560; Invitae). In at least one individual the variant was observed to be de novo. For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg389 amino acid residue in ABCD1. Other variant(s) that disrupt this residue have been observed in individuals with ABCD1-related conditions (PMID: 7825602, 15811009), which suggests that this may be a clinically significant amino acid residue. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C45"). -
