Compositions and methods for treating sensorineural hearing loss using otoferlin dual vector systems

Abstract

The disclosure features compositions and methods for the treatment of sensorineural hearing loss and auditory neuropathy, particularly forms of the disease that are associated with a mutation in otoferlin (OTOF), by way of OTOF gene therapy. The disclosure provides a variety of compositions that include a first nucleic acid vector that contains a polynucleotide encoding an N-terminal portion of an OTOF isoform 5 protein and a second nucleic acid vector that contains a polynucleotide encoding a C-terminal portion of an OTOF isoform 5 protein. These vectors can be used to increase the expression of OTOF in a subject, such as a human subject suffering from sensorineural hearing loss.
