What is Rothmund–Thomson Syndrome?

Rothmund–Thomson Syndrome (RTS) is a rare genetic disorder that affects multiple parts of the body. It was first described by August von Rothmund in 1868 and later by Matthew Thomson in 1936. This condition is characterized by a variety of symptoms, including skin abnormalities, skeletal issues, and an increased risk of cancer.

RTS is caused by mutations in the RECQL4 gene, which plays a crucial role in DNA repair and maintenance.
The syndrome is inherited in an autosomal recessive manner, meaning both parents must carry a copy of the mutated gene for their child to be affected.
RTS affects both males and females equally, with no preference for either gender.
The prevalence of RTS is estimated to be less than 1 in 1,000,000 people worldwide.

Symptoms of Rothmund–Thomson Syndrome

The symptoms of RTS can vary widely among individuals, but there are some common features that many people with the condition experience. These symptoms often appear in early childhood and can progress over time.

One of the hallmark symptoms of RTS is poikiloderma, a skin condition characterized by redness, pigmentation changes, and thinning of the skin.
Children with RTS often develop a distinctive facial rash that starts in infancy and spreads to other parts of the body.
Skeletal abnormalities are common in RTS, including short stature, malformed bones, and delayed bone growth.
People with RTS may have sparse or absent hair, eyebrows, and eyelashes.
Cataracts, or clouding of the eye lens, can develop in individuals with RTS, often at a young age.
Dental problems, such as missing or malformed teeth, are frequently observed in those with RTS.

Increased Cancer Risk

One of the most serious concerns for individuals with RTS is the increased risk of developing certain types of cancer. This risk is significantly higher compared to the general population.

Osteosarcoma, a type of bone cancer, is particularly common in individuals with RTS.
There is also an elevated risk of skin cancer, including basal cell carcinoma and squamous cell carcinoma.
Regular cancer screenings are recommended for individuals with RTS to detect any malignancies early.

Diagnosis and Genetic Testing

Diagnosing RTS can be challenging due to the variability of symptoms. Genetic testing plays a crucial role in confirming the diagnosis.

A clinical diagnosis of RTS is often based on the presence of characteristic symptoms, such as poikiloderma and skeletal abnormalities.
Genetic testing can identify mutations in the RECQL4 gene, confirming the diagnosis of RTS.
Prenatal genetic testing is available for families with a known history of RTS, allowing for early detection.

Treatment and Management

There is no cure for RTS, but various treatments and management strategies can help alleviate symptoms and improve quality of life.

Regular dermatological care is essential to manage skin symptoms and prevent complications.
Physical therapy and orthopedic interventions can address skeletal abnormalities and improve mobility.
Regular eye examinations are important to monitor and treat cataracts.
Dental care is crucial to address any dental abnormalities and maintain oral health.
Cancer surveillance is a key component of managing RTS, with regular screenings to detect and treat malignancies early.

Living with Rothmund–Thomson Syndrome
