Former Top Chef winner Hosea Rosenberg shared an update on his daughter Sophie's journey with an extremely rare and painful genetic disorder. The season 5 champ posted photos of Sophie, 8, via Instagram on Thursday, July 25, and opened up about her experience with multicentric carpotarsal osteolysis - a rare skeletal dysplasia characterized by aggressive resorption of bone and frequently associated with renal failure, according to Rosenberg's foundation, Sophie's Neighborhood. "'How is your daughter Sophie doing?' This is a question I am asked constantly. The answer is complicated.
