Hyper-IgM syndrome type 4
Hyper-IgM syndrome type 4 is a rare immunodeficiency disorder characterized by a decreased ability to fight infections. This condition is one of several types of hyper-IgM syndrome, which are all distinguished by low levels of certain types of antibodies in the blood.
Symptoms[edit | edit source]
People with Hyper-IgM syndrome type 4 have a reduced ability to produce specific types of antibodies, leading to a higher susceptibility to infections. These infections can be recurrent and can affect various parts of the body, including the respiratory system, gastrointestinal tract, and skin.
Causes[edit | edit source]
Hyper-IgM syndrome type 4 is caused by mutations in the activation-induced cytidine deaminase (AID) gene. This gene is involved in the process of class switch recombination, which is essential for the production of different types of antibodies.
Diagnosis[edit | edit source]
Diagnosis of Hyper-IgM syndrome type 4 is based on the presence of characteristic symptoms, a detailed patient history, a thorough clinical evaluation, and specialized tests such as genetic testing to identify mutations in the AID gene.
Treatment[edit | edit source]
Treatment is focused on managing the symptoms and preventing infections. This may include antibiotics, immunoglobulin therapy, and in severe cases, hematopoietic stem cell transplantation.
