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]

Uncertain significance, criteria provided, single submitter	clinical testing	Baylor Genetics	Apr 08, 2020	This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 10, 2021	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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). ClinVar contains an entry for this variant (Variation ID: 1029713). This variant has not been reported in the literature in individuals affected with DHTKD1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with cysteine at codon 24 of the DHTKD1 protein (p.Tyr24Cys). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and cysteine. -
