Labcorp Genetics (formerly Invitae), Labcorp RCV001892916 SCV002162393 uncertain significance 2-aminoadipic 2-oxoadipic aciduria 2023-03-19 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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 not expected to disrupt DHTKD1 protein function. ClinVar contains an entry for this variant (Variation ID: 1391120). This missense change has been observed in individual(s) with clinical features of Charcot-Marie-Tooth disease (PMID: 34169998). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 574 of the DHTKD1 protein (p.Ala574Val).
