BCKDHB branched chain keto acid dehydrogenase E1 subunit beta

Gene ID: 594, updated on 11-Apr-2024
Gene type: protein coding
Also known as: E1B; OVD1B; MSUD1B; BCKDE1B; BCKDH E1-beta

Summary

This gene encodes the E1 beta subunit of branched-chain keto acid dehydrogenase, which is a multienzyme complex associated with the inner membrane of mitochondria. This enzyme complex functions in the catabolism of branched-chain amino acids. Mutations in this gene have been associated with maple syrup urine disease (MSUD), type 1B, a disease characterized by a maple syrup odor to the urine in addition to mental and physical retardation and feeding problems. Alternative splicing at this locus results in multiple transcript variants. [provided by RefSeq, Jan 2016]
