Gene Editing experiment slows down hearing loss

Almost half of all deafness cases are caused by genetic factors, but treating inherited hearing loss is tricky. Now, scientists have shown they can stop a type of progressive hearing loss, caused by a genetic mutation, using the CRISPR-Cas9 gene editing tool. A team led by David Liu at Harvard University injected a CRISPR protein capable of targeting a genetic mutation responsible for a type of deafness into live mice’s ears. The mice used in the study, had a mutated copy of the Tmc1 gene, which causes eventual deafness, alongside one normal copy of the gene. The one-time CRISPR treatment slowed down deafness in the mice.
