The aim of our study was to describe the clinical, electroencephalogram, molecular findings and the diagnostic and therapeutic flow-chart of children with pyridoxine-dependent epilepsies (PDEs). We performed a retrospective observational study on children with PDEs, diagnosed and followed-up in Italian Pediatric Departments. In each centre, the...

Background: The discovery of the inherited disorders of creatine (Cr) synthesis and transport in the last few years disclosed the importance of blood Cr supply for the normal functioning of the brain. These putatively rare diseases share a common pathogenetic mechanism (the depletion of brain Cr) and similar phenotypes characterized by mental...

Background: Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare and underdiagnosed neurometabolic disorder resulting in a complex neurological and non-neurological phenotype, posing diagnostic challenges resulting in diagnostic delay. Due to the low number of patients, gathering high-quality scientific evidence on diagnosis and...

Background: Mutations in genes encoding subunits of the tRNA-splicing endonuclease (TSEN) complex were identified in patients with pontocerebellar hypoplasia 2 (PCH2) and pontocerebellar hypoplasia 4 (PCH4). Objective: We report molecular genetic findings in 12 Italian patients with clinical and MRI findings compatible with PCH2 and PCH4....
