Inherited metabolic disorders characterized by deficient activities of biotin-dependent carboxylases are termed multiple carboxylase deficiency. Partial biotinidase deficiency is defined as 10% to 30% of normal serum activity. Neonatal screening for biotinidase deficiency started in the United States in 1984, which as of 2017 was reported as required in more than 30 countries. Biotinidase deficiency is a deficiency of the enzyme that recycles biotin, due to an inherited genetic mutation. Without biotin, the pathway diverts to 3-hydroxyisovaleric acid. Low serum and urine biotin are not sensitive indicators of inadequate biotin intake.
