Usher syndrome is the most common genetic cause of combined deafness and blindness. More than 400,000 people are affected by this disorder worldwide. There is currently no cure for Usher syndrome.
The Usher Syndrome Coalition is working to raise awareness and accelerate research, while providing information and support to impacted individuals and families. We strive to be the most comprehensive resource for the Usher syndrome community, bridging the gap between researchers and families. Learn more and get involved.
Ganglion cells in the eye generate noise as the light-sensitive photoreceptors die in diseases such as retinitis pigmentosa (RP). Now, neurobiologists have found a drug and gene therapy that can tamp down the noise, improving sight in mice with RP. These therapies could potentially extend the period of useful vision in those with degenerative eye diseases, including, perhaps, age-related macular degeneration.
What this means for Usher syndrome: This type of therapy may also extend the period of useful vision in Usher syndrome.
ProQR Therapeutics N.V., a company dedicated to changing lives through the creation of transformative RNA medicines for the treatment of severe genetic rare diseases, today announced the first patient treated in the Phase 1/2 STELLAR clinical trial for QR-421a in patients with Usher syndrome type 2 or non-syndromic retinitis pigmentosa (RP). Interim data from the trial are expected to be announced by mid-2019. According to David G. Birch, Ph.D., Principal Investigator of STELLAR and Scientific Director of the Retina Foundation of the Southwest in Dallas, Texas, “The STELLAR study is one of the first studies of its kind exploring the impact of ProQR’s RNA therapies on patients with Usher syndrome type 2 due to an Exon 13 mutation. The STELLAR trial will explore whether QR-421a (ProQR’s RNA therapy) can slow disease progression or even reverse it.”
What this means for Usher syndrome: There may be a potential drug available to reverse blindness caused by Usher syndrome.
Researchers at the University of Science and Technology of China injected tiny nanoparticles into mouse eyes that bind the retina into the eyeballs, hence giving them what the team calls ‘super vision.’ The injected nanoparticles bind to photoreceptors and shift the wavelength of light. After the injection, the mice could see normally invisible near-infrared light effectively extending ‘mammalian vision’. Scientists predict that these kinds of nanoparticles could help repair vision in humans who experience loss of retinal function or red color blindness. Additionally, this method is less invasive than other conventional vision repair methods.
What this means for Usher syndrome: This method might be used to increase light sensitivity as vision is lost.
The USH2019 Early Bird Rate has been extended to March 15th and there are new opportunities to connect at this annual Usher syndrome event!
