GTP Cyclohydrolase Deficiency
The below information is taken directly from public registry websites such as ClinicalTrials.gov, EuClinicalTrials.eu, ISRCTN.com, etc. and has not been edited.
The purpose of this study is to identify the dose of Kuvan needed to normalize the levels of tetrahydrobiopterin (BH4) in patients with a Guanosine Triphosphate Cyclohydrolase (GTPCH) deficiency and to asses the potential impact of oral Kuvan on mood and function in individuals with GTPCH deficiency who may be experiencing symptoms of anxiety, depression, fatigue, trouble concentrating, or memory loss. This will be a phase one study. The investigators will monitor patients over a period of three to six months while on the medication. Medication levels will be monitored by measuring the BH4 levels in cerebral spinal fluid (CSF). Patients will undergo a baseline lumbar puncture and two follow-up lumbar punctures for this purpose. The investigators will also monitor emotional function and motor function.
