TWO inseparable sisters born with facial deformities are proving that beauty doesn’t have to be conventional. Asia Williams, 22, and India Walls, 20, were born with Treacher Collins Syndrome (TCS), a genetic craniofacial disorder that affects the bones and tissue in the face and can also affect hearing and eyesight.The sisters, from Marion, Ohio, inherited the syndrome from their mother, Nicole, who inherited it from a great-great grandparent, and taught her girls from day one to embrace their unique beauty. After enduring years of bullying, the sisters - whose hearing has been affected by the syndrome - decided to share their story online to encourage more people with TCS to accept the traits that set them apart from the crowd.
