Treatment

Although there's no way to repair the gene changes that cause Noonan syndrome, treatments can help minimize its effects. The earlier a diagnosis is made and treatment is started, the greater the benefits.

Treatment of the symptoms and complications that occur with Noonan syndrome depends on type and severity. Many of the health and physical issues associated with this syndrome are treated as they would be for anyone with a similar health problem. Taken together, though, the many problems of this disorder require a coordinated team approach.

Recommended approaches may include:

  • Heart treatment. Certain drugs may be effective in treating some kinds of heart problems. If there's a problem with the heart's valves, surgery may be necessary. The doctor also may recommend that heart function be evaluated periodically.
  • Treating low growth rate. Height should be measured three times a year until 3 years of age and then once every year until adulthood to make sure he or she is growing. To evaluate nutrition, the doctor will likely request blood tests. If your child's growth hormone levels are insufficient, growth hormone therapy may be a treatment option.
  • Addressing learning disabilities. For early childhood developmental delays, ask the doctor about infant stimulation programs. Physical and speech therapies may be helpful for addressing a variety of possible issues. In some cases special education or individualized teaching strategies may be appropriate.
  • Vision and hearing treatments. Eye exams are recommended at least every two years. Most eye issues can be treated with glasses alone. Surgery may be needed for some conditions, such as cataracts. Hearing screenings are recommended annually during childhood.
  • Treatment for bleeding and bruising. If there's a history of easy bruising or excessive bleeding, avoid aspirin and aspirin-containing products. In some cases, doctors may prescribe drugs that help the blood to clot. Notify your doctor before any procedures.
  • Treatment for lymphatic problems. Lymphatic problems can occur in many ways and may not require treatment. If they do require treatment, your doctor can suggest appropriate measures.
  • Treatment for genital problems. If one or both testicles haven't moved into proper position within the first few months of life (undescended testicle), surgery may be needed.

Other evaluations and regular follow-up care may be recommended depending on specific issues, for example, regular dental care. Children, teens and adults should continue to have ongoing, periodic evaluations by their health care professional.
