The PTPN22 gene encodes for a protein called tyrosine phosphatase SHP-2, which plays a role in regulating the immune system. This protein helps to regulate the activation and differentiation of immune cells, and it is involved in signalling pathways that control immune cell function.
Variants of the PTPN22 gene have been associated with an increased risk of developing several autoimmune diseases, including rheumatoid arthritis (RA). The specific variant of the PTPN22 gene that has been linked to RA is known as the C1858T variant.
It is important to note that the presence of the PTPN22 gene variant does not guarantee that a person will develop RA. Many people with the variant do not develop the disease, and other factors, such as environmental exposures and lifestyle habits, likely play a role in the onset and progression of RA.
In summary, the PTPN22 gene is involved in regulating the immune system and certain variants of the gene have been associated with an increased risk of developing RA. However, the presence of the variant is just one of many factors that contribute to the development of the disease.
