A team of California researchers has tested a gene-editing tool on mice with the hereditary degenerative disorder retinitis pigmentosa, which routinely leads to blindness, Gizmag.com reports.
The positive results of the animal study may pave the way for use in humans.
The Cedars-Sinai team used a gene-editing tool called CRISPR, which allows researchers to program a protein to switch off genes as desired, in this case targeting a mutated gene that causes the loss of photoreceptors in the eye.
Retinitis pigmentosa is the most prevalent inherited disease of the retina, affecting around 4,000 people in the United States and Europe.
