Lots of people are linking up this NY Times piece detailing the case of a German boy with a peculiar genetic mutation:

The baby, it turned out in the first such documented case in a human, had a double dose of a genetic mutation that causes immense strength in mice and cattle. Drugs are under development that, investigators hope, will use the same principle to help people whose muscles are wasting from muscular dystrophy or other illnesses. Experts say the little boy, now 4½ and still very strong, offers human evidence for the theory behind such drug

The scientists seem to think treatments based on this finding may be available in as little as five to ten years.
