Learn about Marfan's syndrome, the rare genetic disease that Lincoln may have carried.
Abraham Lincoln (1809-1865) probably had Marfan's syndrome (Arachnodactyly), which abnormally lengthens the bones. It is a rare inherited degenerative disease of the connective tissue.
Besides the excessively long bones, there are chest deformities, scoliosis (spine curvature), an arm span that can exceed height, eye problems (especially myopia or nearsightedness), abnormal heart sounds and sparse subcutaneous fat. Researchers identified the gene behind the disease in 1991.
