Between September 2007 and October 2009, mummies were subjected to detailed anthropological, radiological, and genetic studies as part of the King Tutankhamun Family Project. The research showed that Tutankhamun had possibly a mild case of scoliosis, a medical condition where the spine goes to the side. Examination of Tutankhamun's body also revealed deformations in his left foot. The deformation may have forced Tutankhamun to walk with the use of a cane, many of which were found in his tomb. In DNA tests of Tutankhamun's mummy, scientists found DNA from the mosquito-borne parasites that cause malaria. This is currently the oldest known genetic proof of the disease. According to National Geographic, "The malaria would have weakened Tutankhamun's immune system and interfered with the healing of his foot. These factors, combined with the fracture in his left thighbone, which scientists had discovered in 2005, may have ultimately been what killed the young
