Marfan syndrome, a genetic disorder affecting connective tissue, often involves fibrillin-1 abnormalities. Early diagnosis and management, including exercise restriction and medication, are crucial for preventing aortic dissection.

Area of Science:

  • Genetics
  • Cardiology
  • Rheumatology

Background:

  • Marfan syndrome is an autosomal dominant genetic disorder.
  • It is characterized by abnormalities in fibrillin-1, a key component of connective tissue.
  • This condition affects multiple organ systems, including the skeletal, ocular, and cardiovascular systems.

Purpose of the Study:

  • To summarize the clinical presentation and diagnostic challenges of Marfan syndrome.
  • To highlight the importance of early diagnosis and management strategies.
  • To discuss the implications for patient care, including exercise, medication, and monitoring.

Main Methods:

  • Review of clinical features and genetic basis of Marfan syndrome.
  • Discussion of diagnostic criteria and challenges.

  • Outline of current treatment and management recommendations.
  • Main Results:

    • Marfan syndrome presents with diverse clinical manifestations, including skeletal deformities, lens dislocation, and aortic dilatation.
    • Aortic root dilatation is a major complication, increasing the risk of dissection.
    • Diagnosis can be challenging due to the large gene size and numerous mutations, necessitating established diagnostic criteria.

    Conclusions:

    • Early diagnosis of Marfan syndrome is critical for timely intervention and prevention of life-threatening complications like aortic dissection.
    • Management involves lifestyle modifications (e.g., exercise restriction), pharmacotherapy (e.g., beta-blockers), and regular echocardiographic surveillance of the aorta.
    • Family history is essential for identifying at-risk individuals, especially in pauci-symptomatic cases, and pregnancy requires special consideration.
