Description

Glycine encephalopathy with normal serum glycine is a severe metabolic disorder characterized by arthrogryposis multiplex congenita, joint hyperlaxity, lack of neonatal respiratory effort, axial hypotonia, hypertonia with pronounced clonus, and delayed psychomotor development. Some patients may have dysmorphic facial features and/or brain imaging abnormalities. Laboratory studies show increased CSF glycine and normal or only mildly increased serum glycine. Most patients die in infancy. The disorder is similar to, but distinct from, glycine encephalopathy (GCE ) due to mutations in genes encoding the glycine cleavage system (summary by Kurolap et al., 2016).
