Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a rare inherited disorder that affects multiple glands and organs in the body. It is caused by mutations in the AIRE gene, which is responsible for controlling the immune system's response to foreign substances. People with APECED are at an increased risk of developing autoimmune diseases, such as type 1 diabetes, hypothyroidism, and Addison's disease. This disorder is also associated with a number of other conditions, including candidiasis, alopecia, and ectodermal dysplasias.
Symptoms of APECED
People with APECED typically experience a wide range of symptoms. These can include:
• Autoimmune diseases, such as type 1 diabetes, hypothyroidism, and Addison's disease
• Candidiasis, a fungal infection of the skin, mucous membranes, and nails
• Alopecia, or complete or partial hair loss
• Ectodermal dysplasias, which can cause changes in the nails, teeth, and sweat glands
• Abnormal growth of the adrenal glands
• Hypocalcemia, or low calcium levels
• Osteoporosis
• Abnormal development of the skin, hair, and nails
• Recurrent infections
Causes of APECED
APECED is caused by mutations in the AIRE gene, which is responsible for controlling the immune system's response to foreign substances. Mutations in this gene can lead to the body's immune system attacking its own tissues and organs, resulting in the symptoms associated with APECED.
Diagnosis of APECED
APECED is typically diagnosed based on a physical examination, family history, and laboratory tests. Genetic testing can also be used to confirm a diagnosis. Treatment for APECED typically involves managing the symptoms of the disorder and taking medications to control the autoimmune response.
