Disclosed are methods for performing transcription-dependent directed evolution (TRADE) and novel AAV capsids selected using such methods.

An antisense molecule capable of binding to a selected target site to induce exon skipping in the dystrophin gene, as set forth in SEQ ID NO: 1 to 59.

Aspects of the disclosure relate to compositions and methods for exon replacement in a cell or a subject. In some embodiments, the disclosure relates to isolated nucleic acids (and vectors, such as rAAV vectors) encoding one or more guideRNAs (gRNAs) that target an intron-exon boundary; an intronic sequence having a splice signal; and a donor sequence encoding a gene product of a gene of interest, or portion thereof. In some embodiments, compositions described herein are useful for replacing mutant exons associated with certain diseases, for example Duchen's muscular dystrophy (DMD), cystic fibrosis (CF), spinal muscular atrophy (SMA), Rett syndrome, and mucopolysaccharidosis (MPS).

Therapeutic methods and compositions for the in utero or postnatal treatment of diseases associated with alternative splicing are provided. Compositions of the disclosure include delivery nanoparticles with an inner region surrounded by a nucleic acid scaffolding that is, in turn, linked to therapeutic agents that promote healthy mRNA splicing phenotypes in fetal cells when the compositions are delivered to a fetus in utero or in a patient after birth. The nanoparticles preferably include targeting complexes or antibodies that promote endosomal uptake into such cells and escape peptides that release the nanoparticles from endosomes into the cytosol within the cells to allow the therapeutic agents to promote preferred splicing

The present disclosure provides methods and compositions for the treatment of NF-1 and NF-1 mediated conditions. The present disclosure further provides for methods of exon skipping and exon retention and compositions for use in such methods. Such methods of exon skipping and exon retention may be used in the methods of treatment discussed herein. The present disclosure further provides new therapeutic compounds, particularly oligonucleotides, including antisense oligonucleotides, for use in the methods described herein.

Featured are methods for the treatment or prevention of spinal muscular atrophy. Effective dosage regimens are specified. Biomarkers and kits are also provided.

The invention relates to antisense molecules and methods for modulating splicing of polyomavirus T antigen pre-mRNA. In one aspect the invention relates to an antisense oligonucleotide 12 to 30, preferably 17, 18, 19 or 20 to 30 nucleobases in length which comprises a sequence that is the reverse complement of a contiguous stretch of at least 12 nucleobases of a polyomavirus T-antigen pre-mRNA and which antisense oligonucleotide can modulate splicing of said T-antigen pre-mRNA in a cell.

The current disclosure relates to methods and compositions for increasing functional expression of BRD9 in a cell. The methods and compositions can be incorporated into methods for treating cancer through the administration of BRD9 activating therapies. Accordingly, aspects of the disclosure relate to compositions and methods for treating cancer, a pre-malignant disease, or a dysplastic disease in a subject. The method can comprise administering a BRD9 activating therapy to the subject.

A single nucleotide polymorphism (SNP) that results in development of a Type VI collagen, alpha 1 chain-related disorder, and the use of the SNP to identify individuals at risk for developing COL6-related disorders (COL6-RD). Also provided are antisense oligomers for treating individuals at risk for developing COL6-RD, as well as methods for screening compounds for their potential as therapeutic agents.

Antisense oligomer conjugates complementary to a selected target site in the human dystrophin gene to induce exon 52 skipping are described.
