Endogenous tetrahydrobiopterin in humans: circadian rhythm, sex, race, age, and disease status

Circadian rhythm and significant differences between sexes and races in BH<sub>4</sub> concentrations were observed in healthy adults. BH<sub>4</sub> concentrations do not change with age in healthy adults and PKU patients >2 years. BH<sub>4</sub> concentrations were relatively stable between 7:00 and 10:59, providing a window for measurements with minimal variation. The significant difference in BH<sub>4</sub> concentrations between patients with PBD, patients with PKU, and healthy adults could be utilized as a diagnostic tool.

Abstract

Circadian rhythm and significant differences between sexes and races in BH<sub>4</sub> concentrations were observed in healthy adults. BH<sub>4</sub> concentrations do not change with age in healthy adults and PKU patients >2 years. BH<sub>4</sub> concentrations were relatively stable between 7:00 and 10:59, providing a window for measurements with minimal variation. The significant difference in BH<sub>4</sub> concentrations between patients with PBD, patients with PKU, and healthy adults could be utilized as a diagnostic tool.
