These findings establish pathogenic splice signals as genomic targets for sustained suppression of toxic isoforms while retaining canonical gene output and establish pathogenic splice signals as genomic targets for sustained suppression of toxic isoforms while retaining canonical gene output.
Hutchinson Gilford progeria syndrome (HGPS) is a fatal premature aging disorder caused by pathogenic farnesylated lamin A variants that disrupt nuclear architecture and DNA repair. Current therapies, including farnesyltransferase inhibitors, provide only modest survival benefits and lack molecular specificity, while mu...

RNA splicing is a post-transcriptional modification process of precursor mRNA. This process is regulated by the macromolecular complex known as the spliceosome. One of the major components of spliceosomes is the small nuclear ribonucleoprotein (snRNP). Snrpf encodes SmF, a core protein component of the snRNP. Although...

β-Thalassemia is one of the most common inherited disorders worldwide and is caused by mutations affecting β-globin production. β654 mutation (IVS2-654, C > T) is one of the most frequently occurring β-thalassemia alleles in Han Chinese population, which activates a cryptic 3′ splice site and leads to aberrant RNA spli...

Heterozygous loss-of-function variants causing gene dosage reduction underlie many human genetic disorders, yet preclinical mouse models frequently fail to recapitulate human disease phenotypes due to post-translational compensation. Here, we present a generalizable framework to modulate gene dosage by alternative spli...

RNA splicing is a crucial step in eukaryotic gene expression, ensuring the accurate removal of introns and joining of exons to produce mature transcripts. Mutations that alter canonical splice sites or splicing regulatory elements can profoundly affect this process, resulting in aberrant mRNA species and disease. Genet...

In vivo delivery of a locus‐specific DNA base editor to bone tissue is demonstrated, the timing of treatment required for maximum efficacy is delineated, and it is suggested that this system might be tailored for application to other monogenic bone disorders.
