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 |
