Disease Details
Family Health Simplified
- Description
- Ehlers-Danlos syndrome, arthrochalasia type, is a rare genetic disorder characterized by extreme joint hypermobility, skin hyperextensibility, and a tendency for joint dislocations due to defects in collagen synthesis.
- Type
- Ehlers-Danlos syndrome (EDS), arthrochalasia type, is primarily characterized by hypermobility of the joints, skin hyperextensibility, and a tendency to bruise easily. The type of genetic transmission for this subtype of EDS is autosomal dominant.
- Signs And Symptoms
-
Ehlers-Danlos syndrome, arthrochalasia type (EDS type VIIA/B), is a rare subtype of the Ehlers-Danlos syndromes characterized by the following signs and symptoms:
- Severe hypermobility of large joints, which may lead to recurrent dislocations
- Congenital hip dislocations
- Skin hyperextensibility with atrophic scars
- Easy bruising
- Muscle hypotonia (low muscle tone) which can delay motor development
Due to its rarity, detailed knowledge and management often require consultation with a specialized healthcare provider. - Prognosis
- Ehlers-Danlos syndrome, arthrochalasia type (EDS type VIIA and VIIB), is a rare genetic disorder characterized by joint hypermobility, frequent dislocations, and skin hyperextensibility. The prognosis for individuals with this type varies, but it generally involves a lifelong predisposition to joint instability and potential for early osteoarthritis. While the condition can significantly impact quality of life, proper management strategies—including physical therapy, joint protection techniques, and sometimes surgical intervention—can help improve function and reduce complications. Comprehensive care from a multidisciplinary team is often beneficial.
- Onset
- Ehlers-Danlos syndrome, arthrochalasia type, typically has an onset at birth. Patients often display congenital hip dislocation and other joint-related symptoms early in life.
- Prevalence
- Ehlers-Danlos Syndrome, Arthrochalasia Type (EDS type 7A and B) is one of the rare subtypes of Ehlers-Danlos Syndrome. Its exact prevalence is not well documented due to its rarity, but it is considered extremely rare, with only a few dozen cases reported in medical literature.
- Epidemiology
- Ehlers-Danlos syndrome, arthrochalasia type (EDS type VIIA and VIIB), is one of the rare subtypes of Ehlers-Danlos syndrome. Due to its rarity, precise epidemiological data is limited. It is inherited in an autosomal dominant manner and primarily caused by mutations in the COL1A1 or COL1A2 genes, which affect type I collagen production. The exact prevalence is not well established but it is considered extremely rare, with only a small number of cases reported in medical literature.
- Intractability
- Ehlers-Danlos syndrome, arthrochalasia type (EDS type VII or EDSA), is largely considered intractable, meaning that it cannot be cured. Management focuses on symptom control and improving quality of life.
- Disease Severity
- Ehlers-Danlos syndrome arthrochalasia type (EDS type VIIA and VIIB) is one of the less common forms of Ehlers-Danlos syndrome. The severity can vary, but it is generally considered to be moderate to severe. Major characteristics include congenital hip dislocation, skin hyperextensibility, and joint hypermobility, which can lead to recurring joint dislocations. Lifespan is typically normal, but the quality of life can be significantly impacted due to musculoskeletal issues and potential complications.
- Pathophysiology
- Ehlers-Danlos Syndrome, Arthrochalasia Type (EDS type VIIA and B) is a rare genetic disorder characterized by defects in collagen type I. Pathophysiologically, this condition involves mutations in the COL1A1 and COL1A2 genes, leading to defective or insufficient production of type I collagen. This results in hypermobility of the joints, skin hyperextensibility, and other connective tissue abnormalities. The defective collagen disrupts the structural integrity and mechanical properties of connective tissues, causing the clinical manifestations observed in patients with this condition.
- Carrier Status
- Ehlers-Danlos syndrome, arthrochalasia type (EDS type VIIA and VIIB), is an autosomal dominant disorder. As such, carriers are individuals who have one copy of the mutated gene. However, they typically manifest the disease since it is a dominant condition. The genes involved are COL1A1 or COL1A2, and a mutation in either of these genes can cause the syndrome. There is no concept of asymptomatic carriers in autosomal dominant conditions, as carrying one mutated copy generally results in the expression of symptoms.
- Mechanism
-
Ehlers-Danlos syndrome arthrochalasia type (EDS type VIIA and VIIB) is characterized by severe joint hypermobility, congenital dislocations (particularly of the hips), skin hyperextensibility, and other connective tissue abnormalities.
Mechanism:
EDS arthrochalasia type is caused by mutations that affect the primary structure of type I collagen, an essential component of connective tissue, which leads to its improper functioning. This results in weakened connective tissues, leading to the hallmark symptoms of the disease.
Molecular Mechanisms:
1. **COL1A1 and COL1A2 Mutations**: The specific molecular mechanism involves mutations in the COL1A1 or COL1A2 genes, which encode the alpha-1 and alpha-2 chains of type I collagen, respectively. These mutations typically lead to the production of abnormal type I collagen molecules.
2. **Defective Cleavage**: The mutations often result in defective cleavage of the N-terminal propeptide of type I collagen. Proper cleavage is crucial for the formation of mature, functional collagen fibrils. When this process is disrupted, the result is structurally compromised collagen, undermining the integrity of the connective tissue.
3. **Dominant Negative Effect**: The mutations exhibit a dominant negative effect, meaning that the abnormal collagen chains produced from the mutant allele interfere with the normal collagen chains, further compromising collagen structure and function.
Understanding these molecular mechanisms is critical for the development of potential therapies and management strategies for individuals with this type of EDS. - Treatment
-
Ehlers-Danlos syndrome, arthrochalasia type (EDS type VIIA and VIIB), is a rare genetic connective tissue disorder characterized by joint hypermobility, skin hyperextensibility, and other connective tissue abnormalities. Currently, there is no cure for this condition, and treatment focuses on managing symptoms and preventing complications.
1. **Joint and Muscle Care**: Physical therapy is often recommended to strengthen muscles and stabilize joints, reducing the risk of dislocations and injuries.
2. **Pain Management**: Pain relief may be managed through medications, physiotherapy, and sometimes lifestyle adjustments to avoid activities that strain the joints.
3. **Skin Care**: Special attention to skin care may be necessary due to the fragility and hyperextensibility of the skin. This includes gentle handling and avoiding activities that could cause skin injury.
4. **Surgical Interventions**: In severe cases, surgical interventions might be necessary to correct bone abnormalities or severe joint dislocations. However, surgery can be complicated due to the fragile tissues and poor wound healing associated with EDS.
5. **Regular Monitoring**: Regular check-ups with a multi-disciplinary team of specialists such as geneticists, orthopedists, dermatologists, and physical therapists can help in early detection and management of complications.
While ongoing research may offer new insights into treatments, the current approach is largely supportive and symptomatic. - Compassionate Use Treatment
-
Ehlers-Danlos Syndrome, Arthrochalasia Type (EDS-ATH), is a rare genetic disorder characterized by severe joint hypermobility, skin hyperextensibility, and other connective tissue abnormalities. Given its rarity, treatment is primarily symptomatic and supportive.
**Compassionate Use Treatment:**
Compassionate use programs allow patients with serious or life-threatening conditions to access investigational drugs outside clinical trials when no comparable or satisfactory alternative therapy options are available. For EDS-ATH, compassionate use might involve accessing experimental treatments targeting symptoms or underlying genetic mechanisms, although specific drugs are not well-documented due to the rarity of the condition.
**Off-label or Experimental Treatments:**
1. **Physical Therapy:** Customized physical therapy programs may strengthen surrounding muscles and stabilize joints, although not specifically labeled for EDS-ATH.
2. **Joint Stabilization Procedures:** Surgical interventions, though approached with caution due to healing complications.
3. **Pain Management:** Use of analgesics and anti-inflammatory medications, potentially off-label.
4. **Growth Hormone Therapy:** Experimental use in an attempt to address growth issues.
5. **Collagen Supplements:** Investigated for potential to improve connective tissue integrity, though with limited clinical evidence.
Patients should consult specialists in genetics and connective tissue disorders to explore potential compassionate use options and discuss any off-label or experimental treatments. - Lifestyle Recommendations
