Serine-deficiency disorders are treatable neurometabolic diseases. Supplementing L-serine, sometimes with glycine, can improve symptoms like microcephaly and seizures in affected patients.

Area of Science:

  • Biochemistry
  • Neurometabolism
  • Genetics

Background:

  • Serine-deficiency disorders are a novel class of neurometabolic diseases.
  • These conditions stem from impaired L-serine biosynthesis.
  • The severe neurological impact highlights the serine pathway's critical role in brain function.

Purpose of the Study:

  • To review patients with serine-deficiency disorders.
  • To analyze biochemical findings in these patients.
  • To present treatment outcomes with amino acid supplementation.

Main Methods:

  • Literature review of reported cases.
  • Biochemical analysis of patient samples.
  • Assessment of treatment responses.

Main Results:

  • L-Serine is vital for nucleotide and phospholipid synthesis and neurotransmitter production (glycine, D-serine).
  • Disruptions in serine-glycine metabolism may link to psychiatric disorders via NMDA receptor activation.
  • L-serine-derived metabolites are crucial for central nervous system function.

Conclusions:

  • Congenital microcephaly, seizures, and psychomotor retardation are key symptoms.
  • Treatment with L-serine and glycine supplementation can alleviate these symptoms.
  • These findings confirm L-serine's essential role in the central nervous system.
