At first it sounded like science fiction, curing genetic diseases by giving people new genes. Then it seemed like simple fiction: while theoretically possible, gene therapy appeared unlikely to become a true therapeutic option, the field having suffered years of complications and high-profile setbacks. But over the past year, a series of small but intriguing advances has suggested that the technique may hold real future potential.
In September, researchers at the University of Washington reported in the journal Nature that they had produced color vision in squirrel monkeys, which are normally born colorblind. Using a tiny syringe, researchers injected the single missing gene for color vision into the monkeys' eyes. The result was clear: monkeys that previously could not distinguish red, green and gray were easily able to pass a simian equivalent of a color-detection test.
Another study published in the Lancet in October found that gene therapy had restored partial vision to five children and seven adults with a congenital eye disease that causes blindness. And a paper published earlier this month in Science reported the successful treatment of...
