PFN4
PFN4 Gene: The Unsung Hero of Cellular Health
Description
The PFN4 gene, also known as Profillin-4, plays a crucial role in maintaining the structure and function of the body's cells. It encodes a protein called profilin-4, which is part of a family of proteins that regulate the organization of the cellular cytoskeleton. The cytoskeleton is a dynamic network of protein fibers that supports the cell's shape, movement, and intracellular transport.
Associated Diseases
Dysfunction of the PFN4 gene has been associated with several diseases, including:
- Amyotrophic lateral sclerosis (ALS): A progressive neurodegenerative disease that affects motor neurons, leading to muscle weakness and paralysis.
- Frontotemporal dementia (FTD): A group of neurodegenerative disorders characterized by progressive damage to the frontal and temporal lobes of the brain.
- Alzheimer's disease: A form of dementia characterized by memory loss, cognitive impairment, and behavioral changes.
- Parkinson's disease: A neurodegenerative disorder that affects movement, causing tremors, rigidity, and slowness.
Did you Know ?
Recent research suggests that mutations in the PFN4 gene may be a common cause of familial ALS. In a study published in 2022, researchers found that approximately 10% of families with ALS carry a mutation in the PFN4 gene.
