Movement disorders and mRNA therapy in Arginosuccinic aciduria

Dr Sonam Gurung and Dr Julien Baruteau discuss movement disorders in Arginosuccinic aciduria and explain how recent work with mRNA therapy shows potential as a treatment in this condition. The incidence of movement disorder increases with age and contrasts with subtle and limited neuroimaging abnormalities in argininosuccinic aciduria Gurung et al https://doi.org/10.1002/jimd.12691 mRNA therapy corrects defective glutathione metabolism and restores ureagenesis in preclinical argininosuccinic aciduria Gurung et al https://doi.org/10.1126/scitranslmed.adh1334
