Research Abstract

We previously reported a splicing mutation in exon P3A of CHRNA1. We here identified that hnRNP L binds to the mutant site and suppresses splicing of exon P3A. We also reported that intravenous and intramuscular administration of AAV-COLQ to Colq-/-mice improved motor functions, as well as electrophysiological, histochemical, and biochemical features.
