What is Rothmund-Thomson Syndrome?
Rothmund-Thomson syndrome is a rare condition that affects many parts of the body, particularly the skin. People with this condition typically develop redness on the cheeks between ages 3 months and 6 months. Over time the rash spreads to the arms and legs, causing patchy changes in skin coloring, areas of skin tissue degeneration (atrophy), and small clusters of enlarged blood vessels just under the skin (telangiectases). These skin problems persist for life, and are collectively known as poikiloderma. Rothmund-Thomson syndrome is also characterized by sparse hair, eyebrows, and eyelashes; slow growth and small stature; abnormalities of the teeth and nails; and gastrointestinal problems in infancy, such as chronic diarrhea and vomiting. Some affected children develop a clouding of the lens of the eye (cataract), which affects vision. Many people with this disorder have skeletal abnormalities including absent or malformed bones, delayed bone formation, and low bone density (osteopenia)
