The present disclosure relates generally to the treatment of Fragile X Syndrome using a recombinant fusion polypeptide comprising or consisting of a cell penetrating polypeptide, such as HIS or tat, and a Fragile X Mental Retardation protein (FMRP (298)).

The disclosure describes methods of treating humans with Duchenne muscular dystrophy by providing doses of an AAV9 vector that expresses a mini-dystrophin protein in transduced muscle cells.

Methods and products are described herein for the modification of nucleic acids using a CRISPR/Cas9 system. Also described herein are uses of such methods and products for the modification of a target nucleic acid in a cell, in vitro or in vivo. Such methods and products may also be used for prevention or treatment of a condition associated with a target polynucleotide.

Disclosed herein are therapeutic agents capable of increasing the expression level of an epigenetic marker described herein. Also described herein are therapeutic agents that reduce or slow-down an aging phenotype.

Nucleotides encoding a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein are provided herein. Also describe are mRNA constructs that can be used to express CFTR protein in vitro or in vivo. The mRNA constructs can be formulated in a lipid formulation and administered via inhalation to treat cystic fibrosis.

Provided herein are compositions and methods for treating a disorder associated with abnormal RYR2 function (e.g., arrhythmia or heart failure). In some embodiments, method comprises administering to a subject in need thereof an effective amount of a polypeptide comprising a C-terminal domain of Cardiac Myosin binding protein C (MYBPC3) or a nucleic acid or an rAAV encoding such polypeptide.

The present invention relates to recombinant adeno-associated virus (rAAV) delivery of polynucleotides for treating Duchenne Muscular Dystrophy resulting from the duplication of DMD exon 2. The invention provides rAAV products and methods of using the rAAV in the treatment of Duchenne Muscular Dystrophy.

Provided are adeno-associated virus (AAV) compositions that can restore IDS gene function in cells, and methods for using the these AAV compositions to treat disorders associated with reduction of IDS gene function (e.g., Hunter syndrome). Also provided are compositions, systems and methods for making the AAV compositions.

This invention, in one aspect, relates generally to compositions and methods for modulating cellular activities by synthetic opsins. Further, the invention provides method for the use of synthetic opsins for vision restoration and other applications, wherein the amino acid sequence of the synthetic opsin is modified to provide enhanced light sensitivity, kinetics and ion-selectivity.

A nucleic acid comprising a first nucleic acid region comprising a nucleic acid sequence encoding a SMN protein or variant thereof; and a second nucleic acid region comprising one or more target segment(s) of one or more endogenous microRNA(s), wherein the second nucleic acid region is at 3′ of the first nucleic acid region.
