In a laboratory at Boston Children's Hospital a cure for genetic deafness is taking shape. Lead researcher Jeff Holt says that if all goes as planned, children of the future who lose their ability to hear due to genetic mutation will never go deaf.
Holt and his fellow researchers are attacking the problem at its source. They are using engineered viruses to repair damaged genes that make up parts of the inner ear.
"Our strategy was to take a viral vector, remove the viral genes so that it doesn't make anyone sick and to replace those with the . . .
