What this research studies

Deafness and blindness can be very isolating, and Usher syndrome type 1F, caused by a specific gene defect, currently has no treatment. Our team is working on a gene therapy approach using a modified virus to deliver a corrected gene to the inner ear and eye. The challenge is that the gene involved, PCDH15, is too large for standard delivery methods, so we are creating smaller, 'mini' versions of this gene that still work effectively. We hope this innovative strategy can restore hearing and vision for those affected by this devastating condition.

Who could benefit from this research

Good fit: Ideal candidates would be patients diagnosed with Usher syndrome type 1F caused by mutations in the PCDH15 gene.

Not a fit: Patients with other forms of hereditary deafness or blindness not linked to the PCDH15 gene may not benefit from this specific therapy.

Why it matters

Potential benefit: If successful, this gene therapy could offer a treatment for Usher syndrome type 1F, potentially restoring hearing and preventing blindness.

How similar studies have performed: While adeno-associated virus (AAV) vectors have shown promise in delivering gene therapies to the inner ear, the specific 'mini-PCDH15' constructs being developed here are novel.
