- Type
- Weill-Marchesani syndrome 2 (dominant) is characterized by autosomal dominant genetic transmission.
- Signs And Symptoms
-
Weill-Marchesani Syndrome 2 (dominant) is a rare genetic disorder characterized by various signs and symptoms, primarily affecting the eyes and skeleton.
**Signs and Symptoms:**
1. **Ocular Features:**
- Microspherophakia (small, spherical lenses)
- Ectopia lentis (lens dislocation)
- Severe myopia (nearsightedness)
- Glaucoma
- Cataracts
2. **Skeletal Features:**
- Short stature
- Brachydactyly (short fingers and toes)
- Joint stiffness
3. **Facial Features:**
- Distinctive facial appearance, which may include a round face, and a broad nose bridge
These symptoms can vary widely among individuals, even within the same family. - Prognosis
- Weill-Marchesani Syndrome 2 (dominant form) is a rare genetic disorder characterized by short stature, brachydactyly, joint stiffness, and ocular anomalies such as microspherophakia and ectopia lentis. The prognosis can be variable. With appropriate medical management, many individuals can lead relatively normal lives. However, untreated ocular issues might lead to vision impairment or blindness, and joint problems might cause mobility issues. Regular monitoring and early intervention by specialists in ophthalmology, orthopedics, and genetics are essential for improving outcomes and quality of life.
- Onset
- Weill-Marchesani syndrome 2 (dominant) typically has its onset in childhood or adolescence.
- Prevalence
- The prevalence of Weill-Marchesani syndrome 2 (dominant) is not well-documented, making it difficult to provide an exact figure. It is considered a rare genetic disorder.
- Epidemiology
- Weill-Marchesani syndrome 2 (dominant) is a rare genetic disorder. Due to its rarity, detailed epidemiological data on the overall prevalence or incidence is not well-documented. The syndrome is inherited in an autosomal dominant manner, meaning only one copy of the mutated gene is required for the disorder to be expressed.
- Intractability
- Weill-Marchesani syndrome 2 (WMS2) is generally considered a lifelong condition with no cure. While certain symptoms and complications associated with WMS2 can be managed through medical or surgical interventions, the underlying genetic cause of the disease cannot currently be corrected. Therefore, WMS2 can be described as intractable in terms of achieving a complete cure, though symptom management can help improve quality of life.
- Disease Severity
- Weill-Marchesani syndrome 2 dominant (WMS2) typically presents with a range of symptoms that can vary widely in severity. The condition is often characterized by short stature, brachydactyly (short fingers and toes), joint stiffness, and distinctive facial features. Ocular abnormalities, particularly microspherophakia (small and spherical lenses) and ectopia lentis (displacement of the lens), are common and can lead to significant visual impairment. The severity of these manifestations can vary from mild to severe, affecting overall quality of life. Regular monitoring and management of symptoms are crucial for individuals with WMS2.
- Pathophysiology
-
Weill-Marchesani Syndrome 2 (WMS2) is a form of Weill-Marchesani Syndrome caused by mutations in the ADAMTS17 gene. This gene is involved in the formation of extracellular matrix proteins, which are essential for the structural integrity of various tissues.
Pathophysiology:
Mutations in the ADAMTS17 gene lead to dysfunction in the protein's role in facilitating proper formation and maintenance of connective tissues. This results in characteristic features such as microspherophakia (small and spherical lens of the eye), dislocated lenses, short stature, brachydactyly (short fingers), and joint stiffness. These abnormalities primarily affect ocular, skeletal, and sometimes cardiovascular systems. The disruption of normal connective tissue formation due to these genetic mutations underlies the clinical manifestations of WMS2.
Nan (not applicable) is not relevant in the context of the pathophysiology of WMS2. - Carrier Status
- Weill-Marchesani Syndrome 2 (WMS2) is an autosomal dominant genetic disorder. In autosomal dominant inheritance, having just one copy of the altered gene in each cell is sufficient to cause the disorder. Carrier status is less commonly used in the context of autosomal dominant disorders since individuals carrying the mutation typically show some symptoms of the disease. There is no concept of being a "carrier" without showing symptoms as you might find with autosomal recessive conditions. For WMS2, if an individual carries the mutation, they are usually affected by the syndrome to some extent.
- Mechanism
-
Weill-Marchesani syndrome 2, dominant (WMS2) is a rare genetic disorder primarily characterized by short stature, brachydactyly (short fingers and toes), joint stiffness, and eye abnormalities, such as microspherophakia (small, spherical lenses) and ectopia lentis (displacement of the lens).
### Mechanism:
WMS2 is caused by mutations in the ADAMTS10 gene. This gene encodes a protein that is a member of the ADAMTS (A disintegrin and metalloproteinase with thrombospondin motifs) family, which is involved in the assembly of the extracellular matrix and implicated in various biological processes, including the development and maintenance of the eyes, joints, and connective tissue.
### Molecular Mechanisms:
1. **Gene Mutation**:
- Mutations in the ADAMTS10 gene can affect the structure and function of the ADAMTS10 protein.
2. **Extracellular Matrix (ECM) Disruption**:
- The ADAMTS10 protein plays a crucial role in the formation and maintenance of the extracellular matrix. A defective ADAMTS10 disrupts ECM architecture, impacting connective tissues' stability and function.
3. **TGF-β Signaling Pathway**:
- The ADAMTS proteins are involved in the TGF-β (transforming growth factor-beta) signaling pathway, which regulates cell growth, differentiation, and ECM production. Mutations can impair TGF-β signaling, contributing to the development of characteristic features of WMS2.
4. **Lens Development**:
- The ADAMTS10 protein is important for normal eye development. Mutations can lead to abnormal lens shape (microspherophakia) and positioning (ectopia lentis).
These molecular disruptions manifest in the observed clinical features of Weill-Marchesani syndrome 2. - Treatment
-
Weill-Marchesani Syndrome (WMS) is a rare connective tissue disorder that can result in various skeletal, ocular, and cardiovascular abnormalities. Treatment for Weill-Marchesani Syndrome typically focuses on managing individual symptoms and complications. Here are some key aspects:
1. **Ophthalmic Management**: Regular eye examinations are crucial. Treatments may include corrective lenses for vision issues, and in some cases, surgical intervention for lens dislocation (ectopia lentis), glaucoma, or other ocular complications.
2. **Orthopedic Management**: Joint abnormalities and restrictions in movement may require physical therapy, orthopedic surgery, or both to improve mobility and manage pain.
3. **Cardiovascular Monitoring**: Regular check-ups with a cardiologist are recommended to monitor and manage any potential cardiovascular abnormalities, including mitral valve prolapse or other heart issues.
4. **General Supportive Care**: Occupational therapy, special education support, and other individualized interventions may be necessary to address developmental delays and improve quality of life.
It is important for individuals with Weill-Marchesani Syndrome to work closely with a multidisciplinary team of healthcare providers to develop a comprehensive treatment and management plan tailored to their specific needs. - Compassionate Use Treatment
-
Weill-Marchesani Syndrome 2 (WMS2) is a rare genetic disorder characterized by short stature, brachydactyly (short fingers), and eye abnormalities such as microspherophakia, which can lead to glaucoma and other visual impairments. It is inherited in an autosomal dominant manner.
As Weill-Marchesani Syndrome 2 is a rare condition, there are no specific compassionate use treatments, off-label, or experimental treatments widely recognized. However, management typically focuses on addressing the symptoms and may include:
1. **Glaucoma Management**: Use of eye drops, laser therapy, or surgery to reduce intraocular pressure.
2. **Refractive Errors**: Corrective lenses or surgery for severe cases of myopia or other visual disturbances.
3. **Orthopedic Interventions**: Surgery or physical therapy to manage skeletal anomalies as needed.
In some cases, patients and physicians may explore off-label use of medications or treatments designed for related symptoms or conditions, always under careful medical supervision. Experimental treatments, including gene therapies, are an area of ongoing research but are not yet widely available or approved for this condition. Engaging in clinical trials can sometimes provide access to novel therapies being tested for similar genetic disorders. - Lifestyle Recommendations
