Marfan syndrome is a genetic disorder that affects the connective tissues in the body, primarily due to mutations in the FBN1 gene, which encodes the protein fibrillin-1. This syndrome can have a wide range of effects throughout the body, leading to various defects and health issues, including:
1. **Cardiovascular Problems:**
- **Aortic Dilation and Dissection:** The most serious complication, where the aorta (the large vessel that carries blood from the heart) becomes enlarged or tears, which can be life-threatening.
- **Valvular Heart Disease:** Issues with the heart valves, particularly the mitral valve, which can lead to regurgitation.
2. **Skeletal Abnormalities:**
- **Tall Stature:** Individuals with Marfan syndrome are often taller than average due to longer bones.
- **Long Limbs and Fingers:** Distinctively long arms, legs, fingers, and toes (arachnodactyly).
- **Scoliosis:** Curvature of the spine.
- **Chest Deformities:** Pectus excavatum (sunken chest) or pectus carinatum (protruding chest).
3. **Ocular Issues:**
- **Lens Dislocation (Ectopia Lentis):** The lens of the eye may be dislocated, leading to vision problems.
- **Myopia (Nearsightedness):** Commonly occurs in individuals with Marfan syndrome.
4. **Lung Problems:**
- Potential issues with the lungs and respiratory system may arise, such as spontaneous pneumothorax (collapsed lung).
5. **Skin and Other Issues:**
- **Stretch Marks:** Stretch marks may appear without changes in weight.
- **Joint Hypermobility:** Joints may be more flexible than normal, leading to a higher risk of dislocations and joint pain.
6. **Neurological Problems:**
- Increased risk of certain neurological conditions, including headaches, due to spinal and cranial deformities.
Due to the variability in symptoms and severity, not all individuals with Marfan syndrome will experience all of these issues, and the disorders can vary widely from person to person. Early diagnosis and management are crucial to address these potential complications effectively. Regular monitoring by healthcare providers familiar with Marfan syndrome is important for maintaining health and preventing severe complications.
