The present disclosure provides antisense compounds, methods, and compositions for silencing C9ORF72 transcripts. The present disclosure provides antisense compounds, methods, and compositions for the treatment, prevention, or amelioration of diseases, disorders, and conditions associated with C9ORF72 in a subject in need thereof. Also contemplated are antisense compounds and methods for the preparation of a medicament for the treatment, prevention, or amelioration of a disease, disorder, or condition associated with C9ORF72.

The present disclosure provides antisense compounds, methods, and compositions for silencing C9ORF72 transcripts. The present disclosure provides antisense compounds, methods, and compositions for the treatment, prevention, or amelioration of diseases, disorders, and conditions associated with C9ORF72 in a subject in need thereof. Also contemplated are antisense compounds and methods for the preparation of a medicament for the treatment, prevention, or amelioration of a disease, disorder, or condition associated with C9ORF72.

The present disclosure provides oligomeric compounds (including oligomeric compounds that are antisense agents or portions thereof) comprising a modified oligonucleotide having at least one modified internucleoside linking group.

Provided are methods for increasing the amount or activity of FMR1 RNA, and in certain instances of increasing the amount of FMRP protein, in an animal Such methods are useful to prevent or ameliorate at least one symptom of a Fragile X-Spectrum disorder. Such Fragile X-Spectrum disorders include FXS, FXTAS, and FXPOI.

The present invention provides a compound or a pharmaceutically acceptable salt thereof containing a modified oligonucleotide with a length of 8 to 80 consecutive nucleosides, in which the modified oligonucleotide has a nucleobase sequence containing at least 8 consecutive nucleobases contained in a nucleobase sequence of any one of SEQ ID NOs: 3 to 73. With the compound or a pharmaceutically acceptable salt thereof, it is possible to treat a disease or a condition against which inhibition of CALM2 gene expression by controlling of the CALM2 gene expression is effective (particularly, congenital long QT syndrome).

The present invention provides oligomeric compounds. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount activity or expression of the target nucleic acid in a cell.

Disclosed herein are compositions and methods for reducing expression of C9ORF72 mRNA and protein in an animal with C9ORF72 specific inhibitors. Also disclosed herein are compositions and methods of selectively inhibiting a C9ORF72 pathogenic associated mRNA variant by administering an antisense compound targeting the region beginning at the start site of exon 1A to the start site of exon 1B of a C9ORF72 pre-mRNA. Such methods are useful to treat, prevent, or ameliorate neurodegenerative diseases in an individual in need thereof. Such C9ORF72 specific inhibitors include antisense compounds.

The present invention relates to nucleic acid molecules that are complementary to both PAP associated domain containing 5 (PAPD5) and PAP associated domain containing 7 (PAPD7), leading to inhibition of the expression of both PAPD5 and PAPD7 when using a single nucleic acid molecule. The invention also provides for PAPD5 and PAPD7 specific nucleic acid molecules for use in treating and/or preventing a HBV infection, in particular a chronic HBV infection. Also comprised in the present invention is a pharmaceutical composition for use in the treatment and/or prevention of a HBV infection.

Disclosed herein are antisense oligonucleotides that are capable of inducing expression of ubiquitin-protein ligase E3A (UBE3A) from the paternal allele in animal or human neurons. The oligonucleotides target the suppressor of the UBE3A paternal allele by hybridization to SNHG14 long non-coding RNA at the 5′-end of UBE3A-AS, which is downstream of SNORD115-45 snoRNA. Also disclosed are pharmaceutical compositions and methods for treatment of Angelman syndrome.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of LRRK2 RNA in a cell or animal, and in certain instances reducing the amount of LRRK2 protein in a cell or animal. Such compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom or hallmark of a neurodegenerative disease. Such symptoms and hallmarks include ataxia, neuropathy, and aggregate formation. Such neurodegenerative diseases include Parkinson's disease.
