3-Hydroxyisovalerylcarnitine in 3-methylcrotonyl-CoA carboxylase deficiency
A new acylcarnitine was observed in the plasma and urine of a patient with isolated 3-methylcrotonyl-CoA carboxylase deficiency, and analysis by tandem mass spectrometry identified it as a 3-hydroxy-C5-acylc Carnitine, and its origin from leucine was identified.

The molecular basis of 3-methylcrotonylglycinuria, a disorder of leucine catabolism.

Isolated biotin-resistant deficiency of 3-methylcrotonyl-CoA carboxylase presenting as a clinically severe form in a newborn with fatal outcome
The non-responsiveness of the authors' patient to therapy and the fatal outcome indicate the existence of a severe neonatal variant of this otherwise rather benign genetic enzyme deficiency.
