Infants who are diagnosed with biotinidase deficiency and treated before symptoms appear are not expected to develop health problems from this condition. Parents tell us that these children are just like other children except that they require a daily dose of prescribed biotin and regular medical checkups.

Children who begin biotin therapy after symptoms appear usually show rapid improvement, although some effects of the condition may persist such as hearing loss, visual impairments, and developmental delay. Your child's unique response to biotin treatment can best be addressed by your child's doctor. Your doctor or genetic counselor can also help your family locate community resources if your child has special needs.
