One in 500 children is born with hearing impairment, and in 50 to 70 percent of cases a genetic defect is the cause. In a joint research project, a team led by Rüdiger Behr (German Primate Center) and MBExC spokesperson Tobias Moser (University Medical Center Göttingen) in cooperation with scientists from the Max Planck Institute of Experimental Medicine want to establish a gene therapy that can be used to treat hereditary deafness. The method is to be developed on marmoset monkeys and then transferred to human patients. The Leibniz Association has now approved funding of around one million euros for this project.
