Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000033.4(ABCD1):c.1553G>A(p.Arg518Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000912 in 1,096,719 control chromosomes in the GnomAD database, with no homozygous occurrence. There are no hemizygote samples in GnomAD. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R518W) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 16, 2020 | Variant summary: ABCD1 c.1553G>A (p.Arg518Gln) results in a conservative amino acid change located in the AAA+ ATPase domain (IPR003593) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 5.5e-06 in 182500 control chromosomes (gnomAD). The variant c.1553G>A (also known as 1939G>A) has been reported in the literature in numerous individuals affected with Adrenoleukodystrophy (e.g. Imamura_1997, Takano_1999, Dvorakova_2001, Guimaraes_2002, Pan_2005, Coll_2005, Wiens_2019), and in several cases the lack of ALD protein in patient derived fibroblasts was demonstrated (e.g. Imamura_1997, Guimaraes_2002, Coll_2005). These data indicate that the variant is very likely to be associated with disease. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and both of them classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 20, 2024 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 518 of the ABCD1 protein (p.Arg518Gln). This variant is present in population databases (rs398123102, gnomAD 0.001%). This missense change has been observed in individual(s) with ABCD1-related conditions (PMID: 10190819, 12175782, 15811009, 16087056, 21068741, 21700483, 22479560, 23419472, 23566833, 26260157). In at least one individual the variant was observed to be de novo. This variant is also known as c.1939G>A. ClinVar contains an entry for this variant (Variation ID: 92317). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ABCD1 protein function with a positive predictive value of 95%. This variant disrupts the p.Arg518 amino acid residue in ABCD1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 14767898, 16415970). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. - |
