From WikiMD's Wellnesspedia

Other Names[edit | edit source]

Winchester disease; Winchester-Grossman Syndrome

Mechanism[edit | edit source]

  • Winchester syndrome is believed to be inherited through autosomal recessive inheritance.
  • MM2 is responsible for bone remodeling.
  • Bone remodeling is the process in which old bone is destroyed so that new bone can be created to replace it. This mutation causes a multicentric osteolysis and arthritis syndrome.
  • It is hypothesized that the loss of an upstream MMP-2 protein activator MT1-MMP, results in decreased MMP-2 activity without affecting MMP2. The inactivating homoallelic mutation of MT1-MMP can be seen at the surface of fibroblasts.
  • It was determined that fibroblasts lacking MT1-MMP lack the ability to degrade type I collagen which leads to anomalous function.

Symptoms[edit | edit source]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis[edit | edit source]

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Treatment[edit | edit source]

There is no known cure for Winchester syndrome; however, there are many therapies that can aid in the treatment of symptoms. Such treatments can include medications: anti-inflammatories, muscle relaxants, and antibiotics. Many individuals will require physical therapy to promote movement and use of the limbs affected by the syndrome. Genetic counseling is typically prescribed for families to help aid in the understanding of the disease. There are a few clinical trials available to participate in. The prognosis for patients diagnosed with Winchester syndrome is positive. It has been reported that several affected individuals have lived to middle age; however, the disease is progressive and mobility will become limited towards the end of life. Eventually, the contractures will remain even with medical intervention, such as surgery.
