- Description
- Bruck syndrome 2 is a rare autosomal recessive genetic disorder characterized by congenital joint contractures and skeletal fragility due to mutations affecting bone metabolism.
- Type
- Bruck syndrome 2 is characterized as a form of osteogenesis imperfecta with congenital joint contractures. The genetic transmission of Bruck syndrome 2 is autosomal recessive.
- Signs And Symptoms
-
Bruck syndrome 2, also known as autosomal recessive osteogenesis imperfecta with joint contractures, is characterized by the following signs and symptoms:
- Fragile bones that break easily (osteogenesis imperfecta)
- Joint contractures (stiffness and limited movement in the joints)
- Short stature
- Scoliosis (curvature of the spine)
- Bowing of long bones
- Decreased muscle tone (hypotonia)
- Delayed motor development
These symptoms are typically present from birth or early childhood and can vary in severity among affected individuals. - Prognosis
- Bruck syndrome 2 is a rare genetic disorder characterized by bone fragility and joint contractures. The prognosis for individuals with Bruck syndrome 2 can vary. Generally, the condition is severe and can significantly affect quality of life and mobility. Management focuses on supportive care, addressing fractures, and physical therapy to improve function and quality of life. Life expectancy can be variable and largely depends on the severity of the disease and associated complications. Comprehensive medical care and monitoring are essential for managing symptoms and improving outcomes.
- Onset
- Bruck syndrome 2 typically has an onset in infancy or early childhood. This genetic disorder is characterized by brittle bones and joint contractures, which are evident from a young age.
- Prevalence
- Bruch Syndrome 2 (BS2) is an ultra-rare disorder, and exact prevalence data is not well-documented. It is characterized by skeletal abnormalities, including brittle bones and contractures, due to mutations in the FKBP10 gene. Estimations suggest it affects fewer than one in a million people.
- Epidemiology
- Bruck syndrome type 2 is a rare genetic disorder; thus, its exact epidemiology is not well-established due to the limited number of reported cases. As it is inherited in an autosomal recessive manner, the disorder is more likely to occur in populations with higher rates of consanguinity.
- Intractability
- Bruck syndrome type 2 is a rare genetic disorder characterized by bone fragility and joint contractures. While there is no cure for the condition, management typically involves supportive treatments aimed at reducing symptoms, such as physical therapy, orthopedic interventions, and medications to strengthen bones. Therefore, the disease can be considered intractable in terms of achieving a complete cure, but symptom management and quality of life improvements are possible.
- Disease Severity
-
Bruck syndrome 2 is a rare genetic disorder characterized by bone fragility and congenital joint contractures. The severity of this condition can vary widely, even within the same family. Individuals with Bruck syndrome 2 typically experience frequent bone fractures and may have other skeletal abnormalities. Due to the rarity of the condition, specific statistics on severity can be hard to generalize, but the symptoms can range from mild to severe and can significantly impact the quality of life.

- Bruck syndrome 2 is a rare genetic disorder characterized by bone fragility, congenital joint contractures, and pterygia. It is caused by mutations in the PLOD2 gene, which encodes for the enzyme lysyl hydroxylase 2. This enzyme is essential for the proper hydroxylation of lysine residues in collagen molecules, a crucial step in collagen cross-linking. Defective collagen cross-linking leads to weakened structural integrity of the connective tissue, resulting in the clinical manifestations of the disease.
- Carrier Status
- Carrier status for Bruck Syndrome 2 involves having one mutated copy of the FKBP10 gene without showing disease symptoms, as it is inherited in an autosomal recessive manner.
- Mechanism
-
Bruck Syndrome 2 is a rare genetic disorder characterized by congenital joint contractures and bone fragility. It is primarily caused by mutations in the FKBP10 gene, which encodes for the FKBP65 protein, a member of the FK506-binding protein family. This protein plays a crucial role in the proper folding and secretion of type I collagen, a key component of bone and connective tissues.
The mechanism of Bruck Syndrome 2 involves defective collagen biosynthesis due to impaired function of FKBP65. When FKBP65 is dysfunctional, collagen molecules are improperly folded, leading to abnormalities in the extracellular matrix. This results in increased bone fragility and contractures of the joints because the structural integrity and mechanical properties of the bone and connective tissue are compromised. - Treatment
-
Bruck Syndrome type 2 is a rare genetic disorder characterized by brittle bones and joint contractures. Treatment primarily focuses on managing symptoms and improving quality of life. This typically includes:
1. **Orthopedic Interventions**: Surgical procedures to correct bone deformities and stabilize fractures.
2. **Physical Therapy**: Exercises to improve strength, flexibility, and mobility while minimizing the risk of fractures.
3. **Medications**: Bisphosphonates may be prescribed to increase bone density and reduce fracture risk.
4. **Pain Management**: Analgesics to alleviate discomfort.
5. **Assistive Devices**: Braces, wheelchairs, or other mobility aids to support movement and daily activities. - Compassionate Use Treatment
-
Bruck syndrome 2 (BS2) is a rare genetic disorder characterized by bone fragility and congenital joint contractures. Given its rarity, treatment options are often limited and typically focused on managing symptoms and improving quality of life.
**Compassionate Use Treatment:**
1. **Bisphosphonates (e.g., Pamidronate or Alendronate)**: These drugs are commonly used to increase bone density and reduce fracture risk, even though they may not be specifically approved for Bruck syndrome 2.
**Off-label or Experimental Treatments:**
1. **Teriparatide (Forteo)**: Although primarily approved for osteoporosis, teriparatide has been considered for use in increasing bone formation and density in various types of bone fragility disorders.
2. **Cell and Gene Therapy**: These are in very early experimental stages and aim to address the underlying genetic causes of the disorder.
3. **Enzyme Replacement Therapy**: Still in research phases, this approach involves supplementing deficient or malfunctioning proteins that contribute to the symptoms of Bruck syndrome 2.
Clinical trials may also be an option, depending on availability and eligibility criteria. Always consult with a healthcare provider for specific medical advice and treatment options. - Lifestyle Recommendations
