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. In certain embodiments, hybridization results in selective modulation of the amount, activity, or expression of a target Huntingtin gene or Huntingtin transcript in a cell.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of MSH3 RNA in a cell or subject, and in certain instances reducing the amount of MSH3 protein in a cell or subject. These compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom or hallmark of a repeat expansion disease. Such symptoms and hallmarks include brain atrophy, muscle atrophy, nerve degeneration, uncontrolled movement, seizure, tremors, muscle weakness, muscle cramping, difficulty swallowing, difficulty speaking, decreased memory, decreased cognition, anxiety, and depression. Non-limiting examples of repeat expansion diseases that benefit from these compounds, methods, and pharmaceutical compositions are myotonic dystrophy (DM1 and DM2), amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, various polyglutamine disorders, Friedrich's ataxia, Fragile X syndrome, or spinocerebellar ataxia (e.g., SCA1, SCA2, SCA3, SCA6, SCAT, SCA8, SCA10, or SCA17).
