3. Rothmund-Thomson Syndrome Symptoms and Characteristics- redness on the skinjuvenile cataractssaddle nose bone defectshair growth problemscalcium problems ear problems rash on the skin Who is affected?- Rothmund-Thomson Syndrome is genetic, rare, and only has about 300 reported cases. It affects males more than females slightly, with a 2:1 ratio. Most cases are of very young children. If both parents have this syndrome, there’s a 100% chance the child(ren) will receive the mutated genes. Outlook or quality of life- The condition can be treated to a large extent, and children with RTS can have a normal quality of life.
