Rheumatoid arthritis (RA) is a complex disease that is believed to be influenced by both genetic and environmental factors. There are several genetic markers that have been associated with an increased risk of developing RA, including:
It is important to note that having a genetic marker for RA does not guarantee that a person will develop the disease. Many people with these genetic markers do not develop RA, while others who do not have these markers may still develop the disease. A combination of genetic, environmental, and lifestyle factors likely contribute to the development of RA.
- HLA-DRB1 gene: This gene is involved in the immune system's response to foreign invaders and has been strongly linked to RA.
- PTPN22 gene: This gene plays a role in regulating the immune system and has been linked to an increased risk of RA.
- STAT4 gene: This gene is involved in the immune system's response to infection and has been associated with RA.
- TRAF1 and C5 gene: These genes play a role in the immune system's response to inflammation and have been linked to an increased risk of RA.
- CTLA4 gene: This gene helps to regulate the immune system and has been associated with RA.
