Autoimmune Polyendocrine Syndrome (APS) is a group of rare, inherited disorders caused by mutations in certain genes. These mutations can cause the body’s immune system to become overactive, resulting in the production of antibodies that attack the body’s own cells and tissues. This leads to a variety of symptoms, including chronic inflammation, fatigue, joint pain, gastrointestinal problems, and endocrine abnormalities.
The exact cause of APS is not known, however, there are several genetic factors that are thought to be involved in the development of this condition. Mutations in the AIRE gene are one of the most common genetic causes of APS, and are believed to be responsible for up to 80% of all cases. Additionally, mutations in the PTPN22 gene have been associated with a higher risk of APS.
Environmental factors have also been implicated in the development of APS. Exposure to certain toxins and certain viral infections have been known to trigger the immune system to become overactive, leading to the development of APS. Additionally, certain medications, such as corticosteroids, have been known to increase the risk of APS.
The exact cause of APS is still unknown, however, it is believed to be the result of a combination of genetic and environmental factors. Treatment for APS typically involves lifestyle modifications, such as avoiding certain triggers, as well as medications to control inflammation and other symptoms.
