Disease Details
Family Health Simplified
- Description
- Ellis-van Creveld syndrome is a rare genetic disorder characterized by short stature, polydactyly (extra fingers or toes), and various abnormalities of the heart, teeth, and nails.
- Type
- Ellis-van Creveld syndrome is an autosomal recessive disorder.
- Signs And Symptoms
-
Signs and symptoms of Ellis-van Creveld syndrome include:
1. **Short Stature**: Patients typically have a shorter-than-average height.
2. **Polydactyly**: Extra fingers or toes are common, usually involving the little finger side of the hands.
3. **Dental Abnormalities**: Teeth may be malformed or missing. Delayed tooth eruption can also occur.
4. **Nail Dysplasia**: Fingernails and toenails may be underdeveloped or misshapen.
5. **Congenital Heart Defects**: Many individuals have heart issues such as atrial septal defects.
6. **Skeletal Dysplasia**: Bone growth abnormalities, especially in the arms, legs, and ribs.
7. **Cleft Palate or Lip**: Some patients may present with cleft palate or lip.
The severity and combination of symptoms can vary widely among individuals with the syndrome. - Prognosis
- Ellis-van Creveld syndrome often results in a varied prognosis, largely depending on the severity of symptoms and associated complications. Many individuals with this condition can lead relatively normal lives with appropriate medical care and management of symptoms, although complications such as heart defects, respiratory issues, or skeletal abnormalities can impact overall health and longevity. Lifespan can be normal, but it is essential to monitor and address any health concerns promptly.
- Onset
- Ellis-van Creveld syndrome typically presents at birth or during infancy.
- Prevalence
- Ellis-van Creveld syndrome is a rare genetic disorder with a prevalence estimated to be about 1 in 60,000 to 200,000 live births worldwide. In the Old Order Amish population, the frequency is much higher due to a founder effect.
- Epidemiology
- Ellis-van Creveld syndrome (EVC) is a rare genetic disorder. Its prevalence is estimated to be between 1 in 60,000 to 1 in 200,000 live births. The condition is more common in certain populations, such as the Old Order Amish community, where the prevalence is much higher due to a founder effect.
- Intractability
- Ellis-van Creveld syndrome (EVC) is a rare genetic disorder characterized by skeletal abnormalities, heart defects, and other physical findings. It is caused by mutations in the EVC or EVC2 genes. While the skeletal abnormalities and certain physical manifestations are generally chronic and require long-term management, interventions such as corrective surgeries, physical therapy, and management of heart defects can improve quality of life. Thus, aspects of the disease are difficult to completely resolve (intractable), but many symptoms and complications can be managed effectively.
- Disease Severity
- Ellis-van Creveld syndrome is a rare genetic disorder that can have varying degrees of severity. It primarily affects the bones, teeth, and sometimes the heart. Severity can range from mild to severe, depending on the presence and extent of symptoms like short stature, polydactyly (extra fingers or toes), dental abnormalities, and congenital heart defects. Without specific patient details, it is not possible to quantify the exact severity for an individual.

- Pathophysiology
- Ellis-van Creveld syndrome, also known as chondroectodermal dysplasia, is a rare autosomal recessive genetic disorder. It is caused by mutations in the EVC or EVC2 genes, which play vital roles in the Hedgehog signaling pathway, an essential regulator of embryonic development. The disruption in this pathway affects various tissues, leading to the hallmark features of the syndrome: short stature due to disproportionate dwarfism, polydactyly (extra fingers or toes), ectodermal dysplasia (abnormal development of skin, hair, teeth, and nails), and congenital heart defects.
- Carrier Status
- Carrier status for Ellis-van Creveld syndrome is typically determined through genetic testing. It is an autosomal recessive disorder, meaning an individual must inherit two copies of the mutated gene (one from each parent) to express the disease. Carriers have one copy of the mutated gene and one normal gene, and they usually do not show symptoms but can pass the mutated gene to their offspring.
- Mechanism
-
Ellis-van Creveld syndrome (EVC) is a genetic disorder that primarily affects bone growth, leading to skeletal abnormalities, heart defects, and other physical anomalies.
Mechanism:
- The disease is inherited in an autosomal recessive manner, meaning that an individual needs to inherit two copies of the mutated gene (one from each parent) to manifest the syndrome.
Molecular Mechanisms:
- Mutations in the EVC or EVC2 genes located on chromosome 4p16 are responsible for the condition. These genes encode proteins involved in the Hedgehog signaling pathway, which is crucial for cell differentiation and developmental processes, particularly in bones and other tissues.
- Disruption in the Hedgehog signaling pathway due to these mutations impairs the normal growth and development of cartilage and bone, leading to the characteristic features of Ellis-van Creveld syndrome. - Treatment
-
Ellis-van Creveld syndrome is primarily managed through symptomatic treatment rather than a definitive cure. Treatment approaches include:
1. **Orthopedic Interventions**: Corrective surgeries for polydactyly, limb length discrepancies, and other skeletal deformities.
2. **Dental Care**: Regular dental examinations and interventions for potential dental anomalies.
3. **Cardiac Care**: Monitoring and surgical correction of congenital heart defects, if present.
4. **Respiratory Support**: Managing respiratory issues, especially in newborns with thoracic restrictions.
5. **Genetic Counseling**: Providing information and support to affected families.
There is no definitive cure for Ellis-van Creveld syndrome; management focuses on treating the symptoms as they arise. - Compassionate Use Treatment
-
Ellis-van Creveld syndrome, also known as chondroectodermal dysplasia, is a rare genetic disorder involving skeletal abnormalities, heart defects, and other developmental issues. For compassionate use or experimental treatments, the options might include:
1. **Gene Therapy**: Though still in experimental stages, gene therapy aims to correct the underlying genetic mutations.
2. **Growth Hormone Therapy**: Off-label use of growth hormone to manage short stature, though its effectiveness can vary.
3. **Surgical Interventions**: Experimental surgical techniques may be considered to address specific skeletal or cardiac anomalies.
4. **Orthopedic Devices**: Customized experimental orthopedic devices may be used to improve mobility and quality of life.
These options should be pursued under expert medical guidance, considering the patient’s specific circumstances. - Lifestyle Recommendations
-
Ellis-van Creveld syndrome is a rare genetic disorder that primarily affects the bones. Here are some general lifestyle recommendations for managing the condition:
1. **Regular Medical Follow-ups**: Regular visits to healthcare providers, including specialists such as orthopedists, cardiologists, and dentists, are crucial for monitoring and managing symptoms.
2. **Physical Activity**: Engage in low-impact physical activities as recommended by a healthcare provider to maintain muscle strength and overall health, while avoiding activities that may stress the bones excessively.
3. **Nutrition**: A balanced diet rich in calcium and vitamin D can support bone health. Consult a dietitian if necessary.
4. **Orthopedic Support**: Use supportive devices like braces or custom footwear to aid mobility and reduce the risk of fractures.
5. **Dental Care**: Maintain good oral hygiene and visit a dentist regularly since dental abnormalities are common with this condition.
6. **Cardiac Health**: Follow guidelines for managing any heart defects, including medication adherence and dietary modifications as recommended by a cardiologist.
7. **Genetic Counseling**: Families affected by Ellis-van Creveld syndrome may benefit from genetic counseling for understanding the condition and family planning.
Always consult healthcare providers for personalized recommendations tailored to the individual's specific needs and condition severity. - Medication
-
Ellis-van Creveld syndrome (EVC) is a rare genetic disorder that primarily affects the development of bones, teeth, and other physical features. There is no specific medication to treat EVC itself. Management of the condition typically focuses on addressing the symptoms and may involve the following:
1. Surgical interventions: To correct skeletal abnormalities or congenital heart defects often associated with EVC.
2. Dental care: Regular visits to a dentist to manage dental issues.
3. Physical therapy: To improve mobility and manage physical development.
4. Supportive care: Multidisciplinary approach including regular monitoring and symptomatic treatment.
There are no particular medications designed to cure Ellis-van Creveld syndrome, and treatment plans are usually individualized based on the specific needs and symptoms of the patient. - Repurposable Drugs
- Ellis-van Creveld syndrome (EVC) is a rare genetic condition also known as chondroectodermal dysplasia. As of now, there are no specific repurposable drugs that have been identified for treating the core symptoms of EVC. Treatment typically focuses on managing individual symptoms, which may involve various medical specialties such as cardiology, orthopedics, and dentistry. Standard care may include surgeries for congenital heart defects and interventions for skeletal abnormalities.
- Metabolites
- Ellis-van Creveld syndrome is a genetic disorder, primarily affecting bone growth. It does not have specific metabolic biomarkers that are commonly monitored or altered directly due to the syndrome. Instead, its clinical diagnosis is based on characteristic physical features and genetic testing for mutations in the EVC or EVC2 genes.
- Nutraceuticals
- Ellis-Van Creveld syndrome, also known as chondroectodermal dysplasia, is a rare genetic disorder. Currently, there are no specific nutraceuticals recommended for the treatment or management of this condition. The main approach focuses on symptomatic management and supportive care through a multidisciplinary team of healthcare professionals.
- Peptides
- Ellis-van Creveld syndrome, or chondroectodermal dysplasia, is a genetic disorder characterized by skeletal dysplasia, ectodermal dysplasia, and heart defects. It is caused by mutations in the EVC or EVC2 genes. This condition does not have a direct relation to peptides or nanotechnology in its standard diagnosis or treatment methods. However, understanding the molecular biology and genetics involved might eventually lead to the development of peptide-based or nano-based therapeutic strategies in the future. Currently, management is primarily symptomatic, involving multidisciplinary care from orthopedic surgeons, cardiologists, and other specialists.
