Summary

Phenotype

Biochemical disease mechanism

MSUD affects a protein called branched-chain alpha-keto acid dehydrogenase complex (BCKDHC), which is involved in the degradation of branched amino acids (Val, Leu, Ile). BCKDHC consists of four subunits:

subunit name chromosomal gene location MSUD-type
BCKDHA Branched chain keto acid dehydrogenase E1, alpha polypeptide 19q13.1-q13.2 1a
BCKDHB branched chain keto acid dehydrogenase E1, beta polypeptide 6q14.1 1b
DBT Dihydrolipoamide branched chain transacylase E2 1p31 2
DLD dihydrolipoamide dehydrogenase 7q31-q32 3
