...s of nitrogen) floating in the air and stretch it, weakening the bond between the two nitrogen atoms. This makes the nitrogen more likely to link up with hydrogen to create ammonia (NH3)-the useful form with one nitrogen atom combined with three hydrogen atoms.

It causes progressive muscle weakening and death, usually before age 20. No effective therapy exists for the disease. In boys lacking dystrophin, muscles function abnormally, at first enlarging, then degenerating so that fat and scar tissue take over.
