ICD-10: Q77.6

Chondroectodermal dysplasia, also known as Ellis-Van Creveld syndrome (EVC), is a rare genetic disorder characterized by a combination of skeletal dysplasia and ectodermal anomalies. This condition is classified under ICD-10 code Q77.6. Below is a detailed clinical description and relevant information regarding this syndrome.

Clinical Features

Skeletal Abnormalities

Chondroectodermal dysplasia primarily affects the development of bones and cartilage. Key skeletal features include:

• Short Stature: Individuals with EVC typically present with a significantly shorter stature compared to their peers, often due to disproportionate limb length.
• Dysplastic Bones: The condition is associated with abnormalities in the growth and development of bones, particularly affecting the ribs, which may lead to a barrel-shaped chest.
• Polydactyly: Many patients exhibit polydactyly, which is the presence of extra fingers or toes.
• Dental Anomalies: Patients often have dental issues, including hypoplastic enamel and missing teeth, which can lead to significant oral health problems.

Ectodermal Features

In addition to skeletal manifestations, EVC includes ectodermal dysplasia, which may present as:

• Hair and Nail Abnormalities: Individuals may have sparse hair, particularly on the scalp, and nails that are thin or malformed.
• Skin Changes: The skin may exhibit various anomalies, including pigmentation changes or a lack of sweat glands, leading to difficulties in thermoregulation.

Other Associated Features

• Congenital Heart Defects: Some individuals may have congenital heart defects, which can complicate the clinical picture.
• Respiratory Issues: Due to rib deformities, respiratory function may be compromised, leading to potential complications.

Genetic Basis

Chondroectodermal dysplasia is primarily caused by mutations in the EVC gene, which plays a crucial role in the development of cartilage and ectodermal tissues. The inheritance pattern is typically autosomal recessive, meaning that both copies of the gene in each cell have mutations.

Diagnosis

Diagnosis of EVC is based on clinical evaluation, family history, and genetic testing. Radiological imaging can help identify skeletal abnormalities, while genetic testing can confirm mutations in the EVC gene.

Management

Management of chondroectodermal dysplasia is multidisciplinary and may include:

• Orthopedic Interventions: Surgical procedures may be necessary to correct skeletal deformities or to address polydactyly.
• Dental Care: Regular dental check-ups and interventions are crucial to manage dental anomalies.
• Cardiac Monitoring: For those with congenital heart defects, regular cardiac evaluations are essential.
• Supportive Care: Physical therapy and occupational therapy can help improve mobility and daily functioning.

Conclusion

Chondroectodermal dysplasia (ICD-10 code Q77.6) is a complex condition that requires a comprehensive approach to diagnosis and management. Early intervention and a multidisciplinary care team can significantly improve the quality of life for affected individuals. Understanding the clinical features and genetic basis of this syndrome is essential for healthcare providers to offer appropriate care and support.

This condition is classified under ICD-10 code Q77.6. Below is a detailed overview of its clinical presentation, signs, symptoms, and patient characteristics.

Clinical Presentation

Chondroectodermal dysplasia typically presents in early childhood, often at birth or shortly thereafter. The condition is caused by mutations in the EVC gene, which plays a crucial role in the development of cartilage and ectodermal tissues. The clinical features can vary significantly among affected individuals, but several hallmark characteristics are commonly observed.

Signs and Symptoms

Skeletal Abnormalities

• Short Stature: Individuals with EVC often exhibit a significantly shorter stature compared to their peers due to skeletal dysplasia.
• Limb Deformities: Common limb abnormalities include polydactyly (extra fingers or toes), brachydactyly (short fingers), and syndactyly (fusion of fingers or toes).
• Chest Deformities: Affected individuals may have a narrow chest and a prominent sternum, leading to a barrel-shaped thorax.
• Dental Anomalies: Hypoplastic enamel and missing teeth are frequently observed, contributing to dental issues.

Ectodermal Features

• Hair and Skin: Patients may have sparse hair (hypotrichosis) and skin abnormalities, including a lack of sweat glands (hypohidrosis), which can lead to difficulties in thermoregulation.
• Nail Abnormalities: Nails may be thin, brittle, or absent.

Other Clinical Features

• Cardiac Anomalies: Congenital heart defects, such as atrial septal defects, are common in individuals with EVC.
• Respiratory Issues: Some patients may experience respiratory difficulties due to structural abnormalities in the thoracic cavity.
• Intellectual Development: While most individuals have normal intelligence, some may experience developmental delays.

Patient Characteristics

Demographics

• Prevalence: Chondroectodermal dysplasia is a rare condition, with an estimated prevalence of 1 in 60,000 to 1 in 200,000 live births.
• Inheritance Pattern: The disorder follows an autosomal recessive inheritance pattern, meaning that both parents must carry a copy of the mutated gene for a child to be affected.

Age of Onset

• Symptoms are typically evident at birth or during early childhood, with skeletal and ectodermal features becoming more pronounced as the child grows.

Gender

• There is no significant gender predilection; both males and females are equally affected.
