The intracellular concentration of chloride ([Cl(-)]i) determines the strength and polarity of GABA neurotransmission. STE20/SPS1-related proline/alanine-rich kinase (SPAK) is known as an indirect regulator of [Cl(-)]i for its activation of Na-K-2 Cl(-)co-transporters (NKCC) and inhibition of

Type I hyperprolinemia (HPI) is an autosomal recessive disorder caused by proline oxidase deficiency. This enzyme is encoded by the proline dehydrogenase (PRODH) gene on 22q11. The functional consequences of different PRODH mutations on proline oxidase activity have been characterized in vitro. Few

1. The anticonvulsant properties of L-proline, of proline derivatives (trans-4-hydroxy-L-proline, cis-4-hydroxy-D-proline, 3,4-dehydro-D,L-proline) and of D- and L-pipecolic acid were studied alone and in combination with vigabatrin (R/S-4-aminohex-5-enoic acid). 3-Mercaptopropionic acid and

Nucleotide alterations in the gene encoding proline-rich transmembrane protein 2 (PRRT2) have been identified in most patients with benign partial epilepsies in infancy (BPEI)/benign familial infantile epilepsy (BFIE). However, not all patients harbor these PRRT2 mutations, indicating the

This paper documents the case of a female Japanese patient with infantile focal epilepsy, which was different from benign infantile seizures, and a family history of infantile convulsion and paroxysmal choreoathetosis. The patient developed partial seizures (e.g., psychomotor arrest) at age 14

Increased proline levels were found in plasma of a girl with slight psychomotor retardation, epilepsy, obesity, scoliosis, hypocalcaemia, variable lymphocytopenia and facial dysmorphy suggestive of CATCH 22 syndrome. Fluorescence in situ hybridization indicated the presence of a submicroscopic 22q11

Proline-rich transmembrane protein 2 gene (PRRT2) mutations are reported to cause common paroxysmal neurological disorders and show a remarkable pleiotropy. Benign epilepsy with centrotemporal spikes (BECTS) is considered to be the most common epilepsy syndrome in childhood. It is placed among the

α-Aminoadipic semialdehyde and its cyclic form (Δp>1p>-piperideine-6-carboxylate) accumulate in patients with α-aminoadipic semialdehyde dehydrogenase (AASADH; antiquitin; ALDH7A1) deficiency. Δp>1p>-Piperideine-6-carboxylate reacts with pyridoxal 5'-phosphate (PLP) to form a

Epilepsy is a neurological disorder affecting approximately 1% of the worldwide population. Mutations in voltage-gated sodium channels have been identified in several monogenic epilepsy syndromes. Over 800 mutations have been identified in the voltage-gated sodium channel genes SCN1A and SCN2A in

Hyperpolarization-activated cyclic nucleotide-gated channels (HCN) can act as pacemakers in the brain making them strong candidates for driving aberrant hypersynchronous network activity seen in epilepsy. Transcriptional changes in HCN channels occur in several animal models of epilepsy. However,

The N-methyl-(2S,4R)-trans-4-hydroxy-l-proline-enriched fraction (NMP) from Sideroxylon obtusifolium was evaluated as a neuroprotective agent in the intracerebroventricular (icv) pilocarpine (Pilo) model. To this aim, male mice were subdivided into sham (SO, vehicle), Pilo (300 µg/1 µL

A 9-year-old girl with type I hyperprolinemia, who also had photogenic epilepsy, was reported. She showed epileptic discharges and the regression in speech and motor activities, since 7 years of age. Her plasma proline levels were 3 to 4 times higher than control levels. In urine, iminoglycinuria

Hyperprolinemia type II is an autosomal recessive disorder caused by the severe deficiency of delta(1)-pyrroline-5-carboxylate dehydrogenase activity leading to tissue accumulation of proline (Pro). Most patients detected so far show neurological manifestations including epilepsy and mental

DBP (albumin D-site-binding protein), HLF (hepatic leukemia factor), and TEF (thyrotroph embryonic factor) are the three members of the PAR bZip (proline and acidic amino acid-rich basic leucine zipper) transcription factor family. All three of these transcriptional regulatory proteins accumulate
