Abstract: The present invention contemplates-allele-specific gene editing based on targeting a heterozygous single nucleotide polymorphism (SNP) in a protein coding sequence associated with a genetic disease. The data shown herein demonstrates that the outcome of such gene editing creates a nonesense mutation that results in a marked and selective reduction of mutant protein without affecting wild type protein expression. Expression of a single CRISPR-Cas9 nuclease in neurons generated a high frequency of mutations in the targeted HD allele that included both small insertion/deletion mutations and viral vector insertions. Thus, as disclosed herein, allele-specific targeting of InDel and insertion mutations to heterozygous coding SNPs provides a feasible approach to inactivate autosomal dominant mutations that cause genetic disease.

Abstract: The present disclosure relates to antisense oligonucleotides, which target SNCA mRNA (e.g., at an intron exon junction) in a cell, leading to reduced expression of SNCA protein.

Abstract: The present invention relates to the technical field of nucleic acids, and in particular, to a method for precisely preparing a circular RNA with an Anabaena intron self-cleaving ribozyme. By redesigning a target nucleic acid sequence of a linear RNA, selecting a site suitable for precise cleavage by the intron self-cleaving ribozyme, and removing exon sequences from the Anabaena intron self-cleaving ribozyme, precise cyclization of RNAs after in vitro transcription is achieved. The method provided by the present invention solves the problem in the prior art that linear RNAs cannot be precisely cyclized during the process of generating circular RNAs in vitro, and provides an ideal in vitro preparation method for circular RNA applications.
