Summary
Since the introduction of neonatal screening for branched-chain organic acidurias, it has been noted that isolated 3-methylcrotonyl-CoA carboxylase deficiency is probably one of the most frequent organic acidurias. Only a few cases with severe clinical presentation have been described. Profound hypoglycaemia is an uncommon but life-threatening complication.
