"Historians have long puzzled over whether Abraham Lincoln might have had a genetic disorder called Marfan syndrome, but new research has members of the beloved president's family tree wondering if his clumsy gait may actually have been caused by something else. Researchers at the University of Minnesota have discovered a gene mutation in 11 generations of relatives who descended from Lincoln's grandparents. The gene causes spinocerebellar ataxia type 5, a degenerative neurological disorder that affects coordination, including walking, writing, speaking and swallowing. There's a 25 percent chance that Lincoln also inherited the mutation, said Laura Ranum, a genetics professor who led the research."She then went on to explain that Lincoln would now protect a world sworn to fear and hate him, and that yes, he was indeed the best he was at what he did.
