Did Malaria, Bone Disease Kill King Tut?
DNA Analysis of Mummy Yields New Clues to Pharaoh's Death
Feb. 16, 2010 -- Malaria and bone disease may have contributed to the death of King Tut more than 3,300 years ago, a new DNA analysis and other scientific methods indicate.
Many theories have been raised about the death of Tutankhamun, or King Tut, one of Egypt's most famous pharaohs, since his mummy was discovered in 1922. The theories include suggestions that he was murdered or died from an infection after breaking a leg in a fall.
But scientists who used a number of modern methods, including DNA analysis and radiological scans of mummies of Tut and probable close relatives, now report a variety of possible causes of death of Tutankhamun and others, including his grandparents, father, and siblings.
The study, led by Zahi Hawass, PhD, head of Egypt's Supreme Council of Antiquities, includes these points:
- King Tut suffered from avascular bone necrosis, a condition in which poor blood supply to the bone leads to weakening or destruction of an area of bone. This may have been from a rare condition called Kohler's disease that affects the foot.
- He was also found to have a club foot.
- Along with three mummies identified as Tutankhamun's close relatives, Tutankhamun had suffered at some time from malaria, possibly before death, but also perhaps at the time of his demise.
- The researchers write that the bone condition alone would not cause death but in addition to a malaria infection would be a likely cause. "These results suggest avascular bone necrosis in conjunction with the malarial infection as the most likely cause of death of Tutankhamun."
The researchers write that the discovery of several canes and sticks in Tut's tomb, some appearing to have been worn down by use, supports the idea that he had walking problems.
Tutankhamun died in the ninth year of his reign, about 1324 BC, at the age of 19, the researchers say. His mummy was discovered in 1922, and artifacts in the tomb have provided many clues about his life and his family's.
Searching for the Cause of King Tut's Death
Hawass and colleagues studied 11 royal mummies to search for pathological features attributable to inherited disorders, infectious diseases, and blood relationships. They also looked for evidence about what caused King Tut's death. Their research appears in the Feb. 15 issue of The Journal of the American Medical Association.
