Summaries for BCKDK Gene

Entrez Gene Summary for BCKDK Gene

  • The branched-chain alpha-ketoacid dehydrogenase complex (BCKD) is an important regulator of the valine, leucine, and isoleucine catabolic pathways. The protein encoded by this gene is found in the mitochondrion, where it phosphorylates and inactivates BCKD. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

GeneCards Summary for BCKDK Gene

BCKDK (Branched Chain Ketoacid Dehydrogenase Kinase) is a Protein Coding gene. Diseases associated with BCKDK include branched-chain ketoacid dehydrogenase kinase deficiency and autism-epilepsy syndrome due to branched chain ketoacid dehydrogenase kinase deficiency. GO annotations related to this gene include protein serine/threonine kinase activity and [3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring)] kinase activity. An important paralog of this gene is PDK2.

UniProtKB/Swiss-Prot for BCKDK Gene

  • Catalyzes the phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex, the key regulatory enzyme of the valine, leucine and isoleucine catabolic pathways. Key enzyme that regulate the activity state of the BCKD complex.

Disorders for BCKDK Gene

(1) OMIM Diseases for BCKDK Gene (614901)


  • Branched-chain ketoacid dehydrogenase kinase deficiency (BCKDKD) [MIM:614923]: A metabolic disorder characterized by autism, epilepsy, intellectual disability, and reduced branched-chain amino acids. {ECO:0000269 PubMed:22956686, ECO:0000269 PubMed:24449431}. Note=The disease is caused by mutations affecting the gene represented in this entry. A diet enriched in branched amino acids (BCAAs) allows to normalize plasma BCAA levels. This suggests that it may be possible to treat patients with mutations in BCKDK with BCAA supplementation.
