Q77.6

Clinical Causes: Genetic mutations inherited in an autosomal recessive pattern Mutations in the EVC or EVC2 genes, which are involved in cartilage and bone development

Key Symptoms: Short stature due to shortened long bones Polydactyly, especially additional fingers or toes Nail and dental anomalies, including chipped, fused, or missing teeth Congenital heart defects, such as atrial septal defects or ventricular septal defects Cleft palate or other mouth abnormalities Disproportionately small stature with a normal-sized head Skeletal abnormalities, including irregular ribs and limb irregularities Potential respiratory issues due to chest wall abnormalities Dysplastic or missing fingernails and toenails In some cases, abnormalities of the eyes or skin

Diagnosis Path: Diagnosis is typically made through a combination of physical examination, family history, and radiographic imaging. Key diagnostic steps include: - Physical assessment of skeletal and dental features - X-rays to evaluate bone structure and abnormalities - Echocardiogram to detect possible heart defects - Genetic testing to identify mutations in specific genes associated with the syndrome Early diagnosis is crucial for managing potential complications and planning appropriate interventions.

Treatment Protocols: While there is no cure for Ellis-van Creveld syndrome, various treatments aim to manage symptoms and improve functionality: - Surgical procedures to correct skeletal abnormalities and limb deformities - Dental treatments for missing or malformed teeth, including orthodontics and prosthetics - Medical management of congenital heart defects, which may involve surgery or other cardiac interventions - Physical and occupational therapy to support mobility and daily activities - Regular monitoring for potential complications such as respiratory issues or eye abnormalities Multidisciplinary care involving different specialists is often essential for optimal management.
