A 22-YEAR-OLD cites his rare condition, which affects his teeth, hair and sweat glands, with helping him become a model. Brooks Ginnan, from New York, was born with ectodermal dysplasia, a rare genetic disorder. Brooks told BTV: "I believe the statistic is about 1 in 100,000 babies are born with this. It is a condition that affects my teeth, hairs, sweat glands and a number of other aspects of my life.” The 22-year-old has now modelled- both catwalk and editorial - for brands around the world.
