Compositions and methods for editing, e.g., introducing double-stranded breaks, within the TTR gene in combination with administration of a corticosteroid are provided. Compositions and methods for treating subjects having amyloidosis associated with transthyretin (ATTR), in which a guide RNA and a corticosteroid are administered, are provided.

The disclosure relates to double stranded ribonucleic acid (dsRNAi) agents and compositions targeting an RPS25 gene, as well as methods of inhibiting expression of an RPS25 gene and methods of treating subjects having an RPS25-associated disease or disorder, such as a nucleotide repeat expansion disorder, e.g., c9orf72 amyotrophic lateral sclerosis (ALS)/frontotemporal demential (FTD) and Huntington-Like Syndrome Due To C9orf72 Expansions, using such dsRNAi agents and compositions.

The invention relates to a nucleic acid molecule comprising: a. a first region comprising a nucleic acid sequence coding for the protein Cyclin D1, also called CCND1, said first region being controlled by means allowing the expression of said protein, and b. at least one second region, said second region comprising essentially a sequence from 14 to 59 nucleic acids, said second region corresponding to a transcribed region of a gene, said second region containing at least a genetic modification compared to the same region of the corresponding wild-type version of said gene, said second region being genetically isolated from the means allowing the expression of said protein such that said second region is not translated into a peptide.

The present invention provides a method for producing a nucleic acid molecule that can obtain a nucleic acid molecule that binds to a target and does not inhibit a function of the target. The production method for a nucleic acid molecule of the present invention is a method for producing a nucleic acid molecule that binds to a first biological molecule and does not inhibit a function of the first biological molecule, the method including the steps of: (A) bringing a candidate nucleic acid molecule into contact with the first biological molecule to select a nucleic acid molecule that has bound to the first biological molecule as a first selected nucleic acid molecule; and (B) selecting the first selected nucleic acid molecule as an intended nucleic acid molecule.

This disclosure provides, e.g., novel cells having a modification (e.g., insertion or deletion) in the endogenous CD123 gene. The disclosure also provides compositions, e.g., gRNAs, that can be used to make such a modification.

Disclosed herein are antisense oligonucleotide sequences, and methods of use for treating neurological diseases. Described herein are oligonucleotide inhibitors. In various embodiments, the oligonucleotide targets a transcript for the treatment of neurological diseases, including motor neuron diseases, and/or neuropathies. For example, inhibitors of the transcript can be used to treat PD, ALS, FTD, and ALS with FTD.

The disclosure relates to double stranded ribonucleic acid (dsRNAi) agents and compositions targeting a leucine-rich repeat kinase 2 (LRRK2) gene, as well as methods of inhibiting expression of a LRRK2 gene and methods of treating subjects having a LRRK2-associated disease or disorder, e.g., Parkinson's disease, using such dsRNAi agents and compositions.

The present invention relates to RNAi agents, e.g., double stranded RNA (dsRNA) agents, targeting a Fc fragment of IgG receptor and transporter (FCGRT) gene encoding neonatal Fc receptor (FcRn). The invention also relates to methods of using such RNAi agents to inhibit expression of the FCGRT gene or production of the FcRn protein and to methods of preventing and treating a hepatotoxicity-associated disorder, e.g., alcoholic hepatitis, iron overload, and hepatocellular carcinoma.

The present invention is directed to genome editing systems, reagents and methods for the treatment of hemoglobinopathies.

Non-human animal cells and non-human animals comprising CRISPR/Cas synergistic activation mediator system components and methods of making and using such non-human animal cells and non-human animals are provided. Methods are provided for using such non-human animals to increase expression of target genes in vivo and to assess CRISPR/Cas synergistic activation mediator systems for the ability to increase expression of target genes in vivo.
