Splice-modulating antisense oligonucleotides targeting a pathogenic intronic variant in adult polyglucosan body disease correct mis-splicing and restore enzyme activity in patient cells

Abstract excerpt

Adult polyglucosan body disease (APBD) is a rare, adult-onset neurodegenerative disorder caused by loss-of-function variants in the glycogen branching enzyme (GBE1) gene, essential for glycogen biosynthesis. The second most common pathogenic mutation in APBD (c.2053-3358_2053-3350delinsTGTTTTTTACATGACAGGT) is a deep intronic deletion insertion (indel) variant creating an ectopic splice acceptor site, resulting in...
