What killed King Tut?

Through DNA, Hawass’ researchers determined that was indeed the case, and that Tut was married to his sister. Scientists believe that genetics and inherited diseases played a role in Tut’s health because of inbreeding within the family.

“We know there were weaknesses in these mummies, perhaps even cardiovascular problems,” Hawass said.

When researchers scanned Tut’s mummy, they found he not only had severe kyphoscoliosis, or curvature of the spine, but also suffered from a toe malformation known as oligodactyly. The condition made his left foot swell, and it would have caused excruciating pain when he walked.
