A rare inherited disorder that affects the skin and many other parts of the body, including the bones, eyes, nose, hair, nails, teeth, testes, and ovaries. People with Rothmund-Thomson syndrome have an increased risk of osteosarcoma (bone cancer).

An autosomal recessive inherited syndrome usually caused by mutations in the RECQL4 gene. It is characterized by poikilodermatous skin changes, sparse hair, cataracts, small stature, skeletal abnormalities, and an increased predisposition to cancer, particularly osteosarcoma.

An autosomal recessive syndrome occurring principally in females, characterized by the presence of reticulated, atrophic, hyperpigmented, telangiectatic cutaneous plaques, often accompanied by juvenile cataracts, saddle nose, congenital bone defects, disturbances in the growth of HAIR; NAILS; and TEETH; and HYPOGONADISM.

Rothmund-Thomson syndrome (RTS) is characterized by a rash that progresses to poikiloderma; sparse hair, eyelashes, and/or eyebrows; small size; skeletal and dental abnormalities; juvenile cataracts; and an increased risk for cancer, especially osteosarcoma. A variety of benign and malignant hematologic abnormalities have been reported in affected individuals. The rash of RTS typically develops between ages three and six months (occasionally as late as age two years) as erythema, swelling, and blistering on the face, subsequently spreading to the buttocks and extremities. The rash evolves over months to years into the chronic pattern of reticulated hypo- and hyperpigmentation, telangiectasias, and punctate atrophy (collectively known as poikiloderma) that persist throughout life. Hyperkeratotic lesions occur in approximately one third of individuals. Skeletal abnormalities can include radial ray defects, ulnar defects, absent or hypoplastic patella, and osteopenia.

Rothmund-Thomson syndrome, or poikiloderma congenitale, is a rare autosomal recessive disorder attributed to mutations of the RECQL4 helicase gene on 8q24. Key features include early photosensitivity and poikilodermatous skin changes, juvenile cataracts, skeletal dysplasias, and a predisposition to osteosarcoma and skin cancer.

Rothmund-Thomson syndrome is a rare condition that affects many parts of the body, especially the skin, eyes, bones, and teeth. Signs and symptoms can include a characteristic facial rash (poikiloderma); sparse hair, eyelashes, and/or eyebrows; short stature; skeletal (bone) and dental abnormalities; cataracts; premature aging; and an...
