Giving Genetic Disease the Finger

Scientists are closing in on techniques that could let them safely repair almost any defective gene in a patient, opening the door for the first time to treatments for a range of genetic disorders that are now considered incurable.
The breakthrough, announced in the journal Nature in June, relies on so-called zinc fingers, named after wispy amino acid protuberances that emanate from a single zinc ion. When inserted into human cells, the fingers automatically bind to miscoded strands of DNA, spurring the body’s innate repair mechanism to recode the problem area with the correct gene sequence.
