Muscular dystrophy, Selcen type is a rare form of muscular dystrophy that is caused by a mutation in the SELENON gene. It is characterized by progressive muscle weakness and wasting, as well as joint contractures and scoliosis. It is inherited in an autosomal recessive manner and is usually diagnosed in childhood. Treatment is supportive and may include physical therapy, orthopedic surgery, and medications to help manage symptoms.

The symptoms of Selcen type Muscular Dystrophy can vary from person to person, but typically include:

- Muscle Weakness and wasting, usually beginning in the legs and pelvis
- Difficulty walking, climbing stairs, and rising from a seated position
- Joint contractures, which can cause the affected joints to become stiff and difficult to move
- Difficulty with fine motor skills, such as writing and buttoning clothes
- Difficulty with swallowing and speaking
- Scoliosis (curvature of the spine)
- Cardiac abnormalities, such as an enlarged heart or heart valve problems
- Respiratory problems, such as difficulty breathing or a chronic cough
- Fatigue
- Pain in the muscles and joints

The cause of Selcen type muscular dystrophy is unknown. It is believed to be caused by a genetic mutation in the DMD gene, which is responsible for producing dystrophin, a protein that helps keep muscle cells intact. Other possible causes include environmental factors, such as exposure to certain toxins or viruses, or a combination of genetic and environmental factors.

The treatments for muscular dystrophy, selcen type, vary depending on the severity of the condition. Generally, treatments focus on managing symptoms and slowing the progression of the disease. These treatments may include physical therapy, occupational therapy, speech therapy, orthopedic braces, medications, and surgery. Additionally, lifestyle modifications such as a healthy diet, regular exercise, and avoiding activities that may cause injury can help to improve quality of life.

1. Age: Muscular dystrophy, Selcen type is most commonly seen in adults over the age of 40.

2. Gender: Muscular dystrophy, Selcen type is more common in males than females.

3. Genetics: Muscular dystrophy, Selcen type is caused by a genetic mutation in the DMD gene.

4. Family History: Having a family history of muscular dystrophy, Selcen type increases the risk of developing the condition.

5. Ethnicity: Muscular dystrophy, Selcen type is more common in people of European descent.

At this time, there is no cure for Selcen type muscular dystrophy. However, there are medications available to help manage the symptoms of the condition. These medications include corticosteroids, which can help reduce inflammation and improve muscle strength, and immunosuppressants, which can help reduce the body's immune response and slow the progression of the disease. Physical therapy and occupational therapy can also help improve muscle strength and function.
