This invention provides RNA, oligoribonucleotide, and polyribonucleotide molecules comprising pseudouridine or a modified nucleoside, gene therapy vectors comprising same, methods of synthesizing same, and methods for gene replacement, gene therapy, gene transcription silencing, and the delivery of therapeutic proteins to tissue in vivo, comprising the molecules. The present invention also provides methods of reducing the immunogenicity of RNA, oligoribonucleotide, and polyribonucleotide molecules.

Polynucleotides, such as aptamers, comprising at least first one 5-position modified pyrimidine and at least one second 5-position modified pyrimidine are provided, wherein the first and second 5-position modified pyrimidines are different. Methods of selecting and using such polynucleotides, such as aptamers, are also provided.

The disclosure relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the DNAJB 1-PRKAC A fusion gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of DNAJB 1-PRKAC A fusion.

The present disclosure features useful compositions and methods to treat trinucleotide repeat expansion disorders, e.g., in a subject in need thereof. In some aspects, the compositions and methods described herein are useful in the treatment of disorders associated with OGG1 activity.

The present disclosure features useful compositions and methods to treat repeat expansion disorders, e.g., in a subject in need thereof. In some aspects, the compositions and methods described herein are useful in the treatment of disorders associated with MLH3 activity.

Provided are compounds, methods, and pharmaceutical compositions for modulating SCN1A RNA and/or protein in a cell or subject. Such compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom of a developmental or epileptic encephalopathic disease, such as Dravet Syndrome. Such symptoms include seizures, sudden unexpected death in epilepsy, status epilepticus, behavioral and developmental delays, movement and balance dysfunctions, orthopedic conditions, motor and cognitive dysfunctions, delayed language and speech issues, visual motor integration dysfunctions, visual perception dysfunctions, executive dysfunctions, growth and nutrition issues, sleeping difficulties, chronic infections, sensory integration disorders, and dysautonomia.

The present technology relates, in part, to long double-stranded RNA (dsRNA) (e.g., 30 or more base pairs) that inhibits gene expression.

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 214.

The present invention provides method of increasing the efficacy and potency of antisense compounds. In certain embodiments, the invention provides methods for improved cellular uptake.

Provided herein are oligomeric compounds with conjugate groups. In certain embodiments, the oligomeric compounds are conjugated to N-Acetylgalactosamine.
