Search Links: General Info : Protocols : Patient Info

DescriptionBiotin is a vitamin and is an essential cofactor for a number of carboxylase enzymes. Biotinidase is an enzyme involved in the processing of biotin (recycling endogenous biotin and releasing dietary biotin where it is bound to protein). A defect in biotinidase causes biotin deficiency and subsequently leads to multiple carboylase deficiency (MCD) which can provoke life threatening metabolic derrangements.
IndicationCommon clinical features of biotinidase deficiency include: metabolic acidosis, progressive neurological symptoms, hypotonia, ataxia, seizures, intellectual disability, skin rashes, hair loss, immune deficiency.
