The Methuselah Gene by Michael S. Maurer

In The Methuselah Gene, Michael S. Maurer's mesmerizing medical thriller, Alex Morton, a talented but unorthodox scientist, undertakes the care of little Jimmy Higgins who suffers from one of the rarest diseases in the world, progeria, a genetic mutation that grossly accelerates the aging process. Alex's study of progeria yields staggering discoveries about the mother of all diseases, aging. What Alex does not know is that Mother Nature jealously guards her secrets and that his newly developed therapies will lead to calamitous unintended consequences.
