BackgroundIntellectual disability (ID) is part of the Down syndrome (DS) phenotypic spectrum, but the exact molecular pathophysiology of ID in individuals with DS is not yet fully understood, with many research hypotheses still unproven. Basing on previous studies (which suggested a possible role of altered inflammatory response in DS-related...

Higher total homocysteine (tHcy) levels, and C677T and A1298C methylenetetrahydrofolate (MTHFR) polymorphisms, have been reported in preterm or full term newborns with neonatal encephalopathy following perinatal hypoxic-ischemic insult. This study investigated the causal role of tHcy and MTHFR polymorphisms together with other acquired risk...

De novo mutations in the GRIN1 gene have been recently reported as the molecular cause of a broad-spectrum early-onset neurological phenotype. Here, we describe a five-year-old girl with an early-onset epileptic encephalopathy associated with an infantile hyperkinetic movement disorder and oculomotor abnormalities. Whole-exome sequencing...
