Pediatric Biotinidase Deficiency

This inherited disorder is characterized by a deficiency of the biotinidase enzyme. This enzyme is important in metabolizing biotin, a B vitamin. It affects 1 in 60,000 to 75,000 babies in the U.S. and is most common in the people of European descent. Lack of the enzyme can lead to severe acid build up in a child's blood, organs and body systems.
