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]

This sequence change creates a premature translational stop signal (p.Arg410*) in the DHTKD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DHTKD1 are known to be pathogenic (PMID: 23141293, 25860818). This variant is present in population databases (rs397514534, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with 2-aminoadipic and 2-oxoadipic aciduria (PMID: 23141293). ClinVar contains an entry for this variant (Variation ID: 39565). For these reasons, this variant has been classified as Pathogenic. -
