Treatment of deafness by a gene changing genes has proven to be successful.
Harvard scientists have healed dull rats from this treatment, reports Telegraph. They used the 'Crispr CAS-9' method which modifies DNA cells. This method "excludes" the TMC1 gene which causes deafness. People have the same gene, so scientists hope that this method can soon be used by humans too. Crispr CAS-9 technique prevents DNA from injecting a fluid virus that alters it. The modified DNA allows the cells that are responsible for voice to grow normally. It is worth mentioning that this research was published in the journal 'Nature'.
