PURPOSE: Mendelian etiologies for acute encephalopathies in previously healthy children are poorly understood, with the exception of RAN Binding Protein 2 (RANBP2) associated Acute Necrotizing Encephalopathy sub-type 1 (ANE1). We provide clinical, genetic and neuroradiological evidence that biallelic variants in ribonuclease inhibitor (RNH1) confer susceptibility to a distinctive ANE subtype. METHODS: Evaluation of clinical data, neuroradiological studies, genomic sequencing and protein immunoblotting results in eight children from four families who experienced acute febrile encephalopathy...
