About DBT

Cytogenetic location: 1p21.2 Genomic coordinates (GRCh38): 1:100,186,919-100,249,834 (from NCBI)

This gene has 4 transcripts (splice variants), 221 orthologues, 3 paralogues and is associated with 6 phenotypes. Ubiquitous expression in kidney (RPKM 5.8), thyroid (RPKM 4.4) and 25 other tissues.

Summary

The branched-chain alpha-keto acid dehydrogenase complex (BCKD) is an inner-mitochondrial Enzyme complex involved in the breakdown of the branched-chain Amino acids isoleucine, leucine, and valine. The BCKD complex is thought to be composed of a core of 24 transacylase (E2) subunits, and associated decarboxylase (E1), dehydrogenase (E3), and regulatory subunits. This gene encodes the transacylase (E2) subunit. Mutations in this gene result in maple syrup urine disease, type 2. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
