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
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
- 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
Some researchers have speculated that he died from complications from an
injury, blood poisoning, or an embolism caused by a leg fracture or blow to the
head. Others have said the young king may have been murdered because previous
research has suggested death from a blow to the back of the head or possibly a
fall from a chariot.
Between September 2007 and October 2009, royal mummies underwent detailed
genetic, radiological, and anthropological studies. DNA also was extracted from
