Genes affected
DHTKD1 (HGNC:23537): (dehydrogenase E1 and transketolase domain containing 1) This gene encodes a component of a mitochondrial 2-oxoglutarate-dehydrogenase-complex-like protein involved in the degradation pathways of several amino acids, including lysine. Mutations in this gene are associated with 2-aminoadipic 2-oxoadipic aciduria and Charcot-Marie-Tooth Disease Type 2Q. [provided by RefSeq, May 2013]

2-aminoadipic 2-oxoadipic aciduria Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 30, 2021Algorithms 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 520868). This variant has not been reported in the literature in individuals affected with DHTKD1-related conditions. This variant is present in population databases (rs780598300, ExAC 0.05%). This sequence change replaces serine with leucine at codon 209 of the DHTKD1 protein (p.Ser209Leu). The serine residue is moderately conserved and there is a large physicochemical difference between serine and leucine. 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. -
