About Autosomal recessive spastic paraplegia type 25
What is Autosomal recessive spastic paraplegia type 25?
Autosomal recessive spastic paraplegia type 25 (SPG25) is a rare, inherited neurological disorder characterized by progressive muscle weakness and stiffness (spasticity) in the legs. It is caused by mutations in the SPG25 gene, which is responsible for producing a protein called paraplegin. Symptoms usually begin in childhood or adolescence and may include difficulty walking, muscle stiffness, and weakness in the legs. In some cases, the disorder can also affect the arms and hands. There is currently no cure for SPG25, but physical therapy and medications can help manage symptoms.
What are the symptoms of Autosomal recessive spastic paraplegia type 25?
The symptoms of Autosomal recessive spastic paraplegia type 25 (SPG25) vary from person to person, but may include:
- Muscle Weakness and Stiffness in the legs
- Difficulty walking, running, or climbing stairs
- Loss of balance and coordination
- Abnormal gait
- Urinary and/or fecal incontinence
- Muscle spasms
- Pain in the legs
- Fatigue
- Difficulty with fine motor skills
- Speech and language difficulties
- Cognitive impairment
What are the causes of Autosomal recessive spastic paraplegia type 25?
Autosomal recessive spastic paraplegia type 25 (SPG25) is caused by mutations in the KIF5A gene. This gene provides instructions for making a protein called kinesin family member 5A, which is involved in the transport of materials within cells. Mutations in the KIF5A gene lead to the production of an abnormally short, nonfunctional version of the kinesin family member 5A protein. This protein is thought to be involved in the development and maintenance of the long fibers that connect nerve cells in the brain and spinal cord (axons). Without a functional version of this protein, the axons cannot form or function properly, leading to the signs and symptoms of SPG25.
What are the treatments for Autosomal recessive spastic paraplegia type 25?
1. Physical therapy: Physical therapy can help improve muscle strength, flexibility, and coordination. It can also help reduce spasticity and improve balance and gait.
2. Medications: Medications such as baclofen, diazepam, and tizanidine can help reduce spasticity and improve muscle control.
3. Surgery: Surgery may be recommended to help improve mobility and reduce spasticity.
4. Assistive devices: Assistive devices such as walkers, canes, and wheelchairs can help improve mobility and independence.
5. Occupational therapy: Occupational therapy can help improve daily living skills and help with activities of daily living.
6. Speech therapy: Speech therapy can help improve communication skills.
