Sepiapterin reductase deficiency: clinical presentation and evaluation of long-term therapy.

Author information

Service de Neuropédiatrie, CHU Montpellier, France.


Sepiapterin reductase deficiency has recently been recognized as a treatable, inborn error of pterin metabolism. This investigation is the first long-term clinical study demonstrating impressive positive, long-term effects of treatment in two cases of sepiapterin reductase deficiency after 2 and 5 years of treatment respectively. The two patients were not diagnosed before 7 and 13 years of age. These results highlight the importance of cerebrospinal fluid neurotransmitter investigations in childhood encephalopathy, in cases of unexplained early-onset neurologic handicap. Such a widened approach to the diagnostic efforts in early-onset encephalopathy with motor delay during childhood is important, as we have at our disposal a simple and effective treatment.
