Aicardi–Goutieres syndrome in children with idiopathic epilepsy

This article describes 9 clinical cases of Aicardi–Goutières syndrome (AGS) in children admitted to the hospital of the Scientific and Practical Center of Medical Care for Children with Resistant Multifocal Epilepsy. Epilepsy, psychomotor retardation, and a loss of previously acquired skills were diagnosed during the investigation. Targeted exome sequencing in one child revealed a mutation in the RNASEH2B gene responsible for the development of this disease. AGS is an early-onset progressive encephalopathy with basal ganglia calcification, leukodystrophy, lymphocytosis, elevated interferon-alfa levels in the cerebrospinal fluid, and no evidence of viral infection. Noninfectious leukoencephalopathy concurrent with multifocal epilepsy in early childhood suggest that the syndrome is an inherited disease.
