ICD-10: Q87.4

Marfan syndrome is a genetic disorder that affects the body's connective tissue, which provides support to various structures, including organs, blood vessels, and bones. The condition is primarily caused by mutations in the FBN1 gene, which encodes the protein fibrillin-1, essential for the formation of elastic fibers in connective tissue. Below is a detailed clinical description and relevant information regarding ICD-10 code Q87.4, which specifically pertains to Marfan syndrome.

Clinical Features of Marfan Syndrome

1. Skeletal Manifestations

Individuals with Marfan syndrome often exhibit distinctive skeletal features, including:
- Tall stature: Patients are typically taller than average.
- Long limbs and fingers: Known as arachnodactyly, this feature is characterized by long, slender fingers and toes.
- Scoliosis: A curvature of the spine is common, which can lead to postural issues and discomfort.
- Pectus deformities: This includes pectus excavatum (sunken chest) or pectus carinatum (protruding chest).

2. Cardiovascular Complications

Marfan syndrome significantly impacts the cardiovascular system, leading to:
- Aortic dilation and dissection: The aorta, the main artery carrying blood from the heart, may become enlarged (dilated) or tear (dissect), which can be life-threatening.
- Mitral valve prolapse: This condition occurs when the mitral valve does not close properly, potentially leading to regurgitation.

3. Ocular Issues

Patients may experience various eye problems, such as:
- Ectopia lentis: Dislocation of the lens of the eye, which can affect vision.
- Myopia: Nearsightedness is common among individuals with Marfan syndrome.

4. Other Systemic Involvements

Marfan syndrome can also affect other systems, including:
- Pulmonary complications: Such as spontaneous pneumothorax (collapsed lung).
- Skin and integumentary issues: Stretch marks and skin elasticity changes may occur.

Diagnosis and Management

Diagnosis

Diagnosis of Marfan syndrome is typically based on clinical criteria, including the presence of characteristic features and family history. Genetic testing can confirm mutations in the FBN1 gene, aiding in diagnosis, especially in atypical cases.

Management

Management of Marfan syndrome is multidisciplinary and may include:
- Regular cardiovascular monitoring: Echocardiograms are essential to assess heart and aorta health.
- Surgical interventions: Procedures may be necessary to repair or replace affected heart valves or to address aortic dilation.
- Vision correction: Glasses or contact lenses may be prescribed for refractive errors, and surgical options may be considered for lens dislocation.

Marfan syndrome is a genetic disorder that affects connective tissue, leading to a variety of systemic manifestations. The diagnosis of Marfan syndrome, particularly for the ICD-10 code Q87.4, involves a combination of clinical criteria, family history, and genetic testing. Below, we outline the key criteria used for diagnosis.

Clinical Criteria

The diagnosis of Marfan syndrome is primarily based on the Ghent criteria, which include the following components:

1. Major Criteria

• Aortic Dilation or Dissection: Enlargement of the aorta or aortic dissection is a significant indicator of Marfan syndrome. This can be assessed through imaging techniques such as echocardiography or MRI.
• Ectopia Lentis: Dislocation of the lens of the eye is a classic feature of Marfan syndrome, often identified during an eye examination.
• Skeletal Features: Characteristic skeletal abnormalities include tall stature, long limbs, arachnodactyly (long fingers), scoliosis, and chest deformities (pectus excavatum or pectus carinatum).

2. Minor Criteria

• Joint Hyperflexibility: Increased flexibility in joints can be observed in individuals with Marfan syndrome.
• Flat Feet: Pes planus (flat feet) is another common feature.
• Skin Changes: Stretch marks (striae) that occur without significant weight change can be indicative.
• Pulmonary Complications: Spontaneous pneumothorax or other lung issues may be present.

Family History

A positive family history of Marfan syndrome can support the diagnosis, especially if a first-degree relative has been diagnosed with the condition. Genetic inheritance follows an autosomal dominant pattern, meaning that a child has a 50% chance of inheriting the disorder if one parent is affected.

Genetic Testing

While clinical criteria are essential for diagnosis, genetic testing can confirm the presence of mutations in the FBN1 gene, which encodes the connective protein fibrillin-1. This testing is particularly useful in cases where the clinical features are not fully developed or when there is uncertainty in the diagnosis.

Conclusion

In summary, the diagnosis of Marfan syndrome for the ICD-10 code Q87.4 relies on a combination of major and minor clinical criteria, family history, and genetic testing. The Ghent criteria serve as a comprehensive framework for healthcare providers to assess and confirm the diagnosis effectively. Early diagnosis and management are crucial to mitigate the risks associated with cardiovascular and skeletal complications associated with the syndrome.
