Biopterin depression

A number of disorders of biopterin regulation exist. Single-gene defects affecting the gene GCH1 block the first step in biopterin synthesis, and lead to dopamine-responsive dystonia, also known as Segawa's syndrome. This is due to the role of BH4 in synthesising neurotransmitters, including Dopamine, and is treated with supplementation with levodopa, which does not require BH4 for conversion to dopamine. GCH1 defects are autosom… WebJul 9, 2009 · For all depressed patients red-cell folate was significantly correlated with CSF 5HIAA and homovanillic acid (HVA).
