3-Phosphoglycerate dehydrogenase deficiency: description of two new cases in Tunisia and review of the literature.
The two first unrelated Tunisian families with 3-PGDH deficiency confirmed by biochemical and genetic study are reported on.
3-phosphoglycerate dehydrogenase deficiency: a case report of a treatable cause of seizures.
A 4 1/2-year-old boy who presented with congenital microcephaly, psychomotor retardation, hypertonia, strabismus, and drug-resistant seizures due to 3-PGDH deficiency responded to L-serine and glycine supplementation only.
Infantile Serine Biosynthesis Defect Due to Phosphoglycerate Dehydrogenase Deficiency: Variability in Phenotype and Treatment Response, Novel Mutations, and Diagnostic Challenges
6 individuals from 3 families with infantile phosphoglycerate dehydrogenase (PGDH) deficiency who presented with psychomotor delay, growth failure, microcephaly, and spasticity were presented.
Phosphoserine aminotransferase deficiency: a novel disorder of the serine biosynthesis pathway.
The first two identified cases of phosphoserine aminotransferase deficiency has been identified in two siblings who showed low concentrations of serine and glycine in plasma and cerebrospinal fluid and mutational analysis revealed compound heterozygosity for two mutations in the PSAT1 gene in both siblings.
On the phenotypic spectrum of serine biosynthesis defects
Previous reports of serine biosynthesis defects and mutations in the PHGDH, PSAT1, and PSPH genes are reviewed, the variability in the phenotypes associated with serine Biosynthesis defects are discussed, and the vital roles ofserine and the potential consequences of its deficiency are elaborate.

Although further characterization of MRI findings in other patients is required, microencephaly with simplified gyral pattern could provide imaging clues for this rare metabolic disorder.
Phosphoglycerate dehydrogenase (PHGDH) deficiency without epilepsy mimicking primary microcephaly
In a cohort of patients referred for primary microcephaly, compound heterozygosity for two unreported variants in PHGDG was identified by exome sequencing in a pair of sibs who died aged 4.5 months and 4.3 years, but never had seizures.
A serine synthesis defect presenting with a Charcot-Marie-Tooth-like polyneuropathy.
This case expands the phenotypic spectrum of 3-phosphoglycerate dehydrogenase deficiency and should be added to the list of investigations performed in patients with Charcot-Marie-Tooth–like polyneuropathy, especially if it is associated with psychomotor delay and congenital cataracts.
An update on serine deficiency disorders
The use of age-related reference values for serine in CSF and plasma can be of great help in establishing a correct diagnosis of serine deficiency, in particular in newborns and young children.
Two new cases of serine deficiency disorders treated with l-serine.


Congenital microcephaly and seizures due to 3-phosphoglycerate dehydrogenase deficiency: Outcome of treatment with amino acids
The first follow-up data of amino acid therapy in five patients treated for 3–7.5 years is reported, showing a major reduction in seizure frequency and a progress of psychomotor development in one patient, diagnosed early and treated with a high dosage of L-serine.
Molecular characterization of 3-phosphoglycerate dehydrogenase deficiency--a neurometabolic disorder associated with reduced L-serine biosynthesis.
The data presented in this paper suggest an important role for PHGDH activity and L-serine biosynthesis in the metabolism, development, and function of the central nervous system.
L-serine and glycine serve as major astroglia-derived trophic factors for cerebellar Purkinje neurons.
It is demonstrated that l-serine (l-Ser) and glycine (Gly) also are glia-derived trophic factors that mediate the troPHic actions of glial cells on Purkinje neurons.
Blockade of NMDA receptors and apoptotic neurodegeneration in the developing brain.
Blockade of N-methyl-D-aspartate (NMDA) glutamate receptors for only a few hours during late fetal or early neonatal life triggered widespread apoptotic neurodegeneration in the developing rat brain, suggesting that the excitatory neurotransmitter glutamate, acting at NMDA receptors, controls neuronal survival.
