ICD-10: Q87.43

Marfan syndrome is a genetic disorder that affects connective tissue, leading to a variety of systemic manifestations, particularly in the skeletal, cardiovascular, and ocular systems. The ICD-10-CM code Q87.43 specifically refers to Marfan syndrome with skeletal manifestations, highlighting the importance of recognizing the skeletal abnormalities associated with this condition.

Clinical Description of Marfan Syndrome

Overview

Marfan syndrome is caused by mutations in the FBN1 gene, which encodes the protein fibrillin-1, essential for the integrity of connective tissue. This disorder is inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is necessary for the manifestation of the syndrome. The clinical presentation can vary widely among individuals, but certain features are commonly observed.

Skeletal Manifestations

The skeletal manifestations of Marfan syndrome are particularly significant and can include:

• Tall Stature: Individuals with Marfan syndrome often exhibit an above-average height due to excessive growth.
• 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), which can affect respiratory function.
• Joint Hypermobility: Many individuals experience increased flexibility in their joints, which can lead to joint pain and dislocations.

Other Associated Features

In addition to skeletal manifestations, Marfan syndrome can affect other systems:

• Cardiovascular System: Aortic dilation and regurgitation are critical concerns, as they can lead to life-threatening complications.
• Ocular System: Lens dislocation and myopia are common ocular manifestations, which can impair vision.
• Pulmonary System: Spontaneous pneumothorax may occur due to structural weaknesses in the lung tissue.

Diagnosis and Management

Diagnosis of Marfan syndrome typically involves a combination of clinical evaluation, family history, and genetic testing. The Ghent criteria are often used to establish a diagnosis, which includes assessing major and minor criteria across various systems.

Management of Marfan syndrome is multidisciplinary and may include:

• Regular Monitoring: Cardiovascular assessments, including echocardiograms, are essential to monitor aortic dilation.
• Surgical Interventions: In cases of significant aortic dilation or severe skeletal deformities, surgical options may be necessary.
• Physical Therapy: To address joint hypermobility and improve posture, physical therapy can be beneficial.

Conclusion

ICD-10 code Q87.43 captures the essence of Marfan syndrome with skeletal manifestations, emphasizing the importance of recognizing the skeletal abnormalities that accompany this genetic disorder. Early diagnosis and comprehensive management are crucial in improving the quality of life and reducing the risk of serious complications associated with Marfan syndrome. Regular follow-ups and a tailored approach to treatment can help individuals manage their symptoms effectively and maintain a better quality of life.
