About Distal myopathy, Welander type

What is Distal myopathy, Welander type?

Distal myopathy, Welander type is a rare inherited disorder that affects the muscles of the arms and legs. It is characterized by progressive muscle weakness and wasting (atrophy) that begins in the hands and feet and spreads to the arms and legs. Symptoms usually begin in childhood or adolescence and may include difficulty walking, climbing stairs, and lifting objects. Other symptoms may include muscle cramps, joint stiffness, and difficulty with fine motor skills.

What are the symptoms of Distal myopathy, Welander type?

The symptoms of Distal myopathy, Welander type can vary from person to person, but typically include:

-Muscle Weakness in the lower arms and legs
-Difficulty walking, climbing stairs, and standing up from a seated position
-Muscle cramps and stiffness
-Muscle wasting
-Difficulty with fine motor skills such as writing and buttoning clothes
-Foot drop
-Difficulty with balance and coordination
-Fatigue
-Difficulty with swallowing and speaking

What are the causes of Distal myopathy, Welander type?

Distal myopathy, Welander type is caused by mutations in the DYSF gene. This gene provides instructions for making a protein called dysferlin, which is found in muscle fibers. Dysferlin helps to repair damage to the muscle membrane. Mutations in the DYSF gene reduce or eliminate the production of dysferlin, leading to progressive muscle weakness and wasting (atrophy).

What are the treatments for Distal myopathy, Welander type?

The treatments for Distal myopathy, Welander type, are focused on managing the symptoms and slowing the progression of the disease. Treatment options may include physical therapy, occupational therapy, speech therapy, orthopedic braces, and assistive devices. Medications such as corticosteroids, immunosuppressants, and anticonvulsants may also be prescribed to help reduce muscle inflammation and pain. In some cases, surgery may be recommended to correct joint deformities or to improve mobility.

What are the risk factors for Distal myopathy, Welander type?

1. Autosomal dominant inheritance
2. Mutations in the DYSF gene
3. Age of onset typically between 20 and 40 years
4. Proximal muscle weakness
5. Muscle wasting
6. Muscle cramps
