Fumarate Hydratase Deficiency

Fumarate hydratase deficiency (FHD) is a rare disorder characterized by excessive urinary excretion of fumarate, severe neurologic impairment, seizures, hypotonia, growth and developmental delay, structural brain malformations, dysmorphic facial features, and neonatal polycythemia with death typically occurring within the first decade. There have been approximately 30 patients with FHD described in the literature.
