Biotinidase deficiency is an autosomal recessive metabolic disorder that affects the cleavage of biotin. Family studies of the index case found that both parents are usually carriers and siblings have the altered gene, but only homozygotes have manifestations that vary depending on the deficiency grade. Mothers may have moderate deficiency and be asymptomatic; biotin deficiency in pregnant women causes defects in children. In a study, using human cells exposed to biotin deficiency, cell growth decreased contributing to the development of cleft palate. In newborns, biotinidase deficiency has been associated with VACTERL syndrome and annular pancreas. The case of an infant with biotinidase deficiency and congenital defect of the vascular ring is presented. This defect surrounds and compresses the trachea and esophagus, disturbing swallowing and breathing. Infant was supplemented with biotin and surgically intervened with excellent results.
