Marfan syndrome
Burridge suggested that Akhenaten may have suffered from Marfan syndrome, which, unlike Frölich's, does not result in mental impairment or sterility. Marfan sufferers tend towards tallness, with a long, thin face, elongated skull, overgrown ribs, a funnel or pigeon chest, a high curved or slightly cleft palate, and larger pelvis, with enlarged thighs and spindly calves, symptoms that appear in some depictions of Akhenaten. Marfan syndrome is a dominant characteristic, which means sufferers have a 50% chance of passing it on to their children. However, DNA tests on Tutankhamun in 2010 proved negative for Marfan syndrome.
