Autoimmune Polyendocrinopathy Syndrome is an autoimmune disorder that is caused by a mutation in the AIRE gene. This gene is found on chromosome 21 and is responsible for the production of a protein that helps regulate immune responses to foreign substances. The AIRE protein helps to control the body’s response to antigens, which are substances that the body recognizes as foreign. Without the proper functioning of the AIRE protein, the body’s immune system can become overactive and attack its own tissues and organs, resulting in the symptoms of Autoimmune Polyendocrinopathy Syndrome.
The symptoms of this disorder can vary widely, depending on which organs are being attacked. Generally, symptoms include chronic inflammation of the skin, joints, and eyes, as well as the endocrine glands, such as the thyroid gland, pancreas, and adrenal glands. Other symptoms can include recurrent infections, autoimmune disorders like Hashimoto’s thyroiditis, and an increased risk of developing some types of cancers.
The AIRE gene mutation is inherited in an autosomal recessive pattern, meaning both parents must pass on the mutated gene for the child to be affected. If only one parent passes on the mutated gene, the child will be a carrier of the disorder, but will not show any symptoms. Currently, there is no cure for Autoimmune Polyendocrinopathy Syndrome, but there are treatments available to help manage the symptoms and reduce the risk of complications.
