Abstract

There are several inherited disorders that affect biotin metabolism; these are holocarboxylase synthetase (HCS) deficiency, biotinidase deficiency, and biotin-responsive basal ganglia disease. Each of these disorders is inherited as an autosomal recessive trait. Untreated, symptomatic individuals usually develop a variety of neurological symptoms, some of which are caused by the accumulation of abnormal organic acids associated with multiple carboxylase deficiency. Most importantly, the symptoms of each condition can be improved or prevented by early detection and treatment with pharmacological doses of biotin. This chapter will discuss these biotin-responsive disorders.
