Disease Sources Become Clearer

In a finding that would have been impossible before the completion of the human genome map, scientists have found the bit of DNA that causes inherited diseases in families. A Houston researcher, who himself suffers from a recessive genetic disease, conducted one study. "We tried every other method for 25 years to find out which mutation was important," the scientist told Reuters. "With this methodology we were able to do it. This is the first time whole genome sequencing has applied to actually find the cause of a disease."
