WebJan 1, 2024 · Elevated hydroxyisovalerylcarnitine (C5OH) can be seen in 3-methylcrotonyl-CoA carboxylase (3-MCC) deficiency (OMIM 210200; Schulze et al., 2003). Concurrent elevation of C3 and C5OH indicates multiple carboxylase deficiency, usually due to biotinidase or holocarboxylase synthetase deficiency (Burri et al., 1981, Wolf et al., 1985 ). WebPossible Causes: Elevated C5OH is the primary marker for three defects of leucine (LEU) catabolism. These are 3-methylcrotonyl co-A carboxylase deficiency (3-MCC), 3 …
