Invitae RCV001041848 SCV001205493 pathogenic Adrenoleukodystrophy 2019-12-20 criteria provided, single submitter clinical testing This sequence change replaces histidine with aspartic acid at codon 283 of the ABCD1 protein (p.His283Asp). The histidine residue is highly conserved and there is a moderate physicochemical difference between histidine and aspartic acid. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has been observed in individuals and families affected with X-linked adrenoleukodystrophy (PMID: 21300044, 16415970). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant disrupts the p.His283 amino acid residue in ABCD1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23469258, 21300044). 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.
