ICD-10 code: D81.6
Disease category: D81: Combined immunodeficiencies
Understanding Major Histocompatibility Complex Class I Deficiency
Major histocompatibility complex (MHC) class I molecules are essential for the immune system to recognize and eliminate foreign invaders, such as viruses and bacteria. These molecules are found on the surface of most cells in the body and play a crucial role in presenting antigens to T cells, which are immune cells that help fight infections.
Individuals with major histocompatibility complex class I deficiency have a genetic defect that causes their immune system to function improperly. This condition is rare, affecting only a small number of people worldwide.
Symptoms
Individuals with major histocompatibility complex class I deficiency may experience recurrent bacterial, viral, and fungal infections. These infections may be severe and difficult to treat, and can affect various parts of the body, including the skin, lungs, and gastrointestinal tract. In some cases, individuals may also develop autoimmune disorders, which occur when the immune system attacks healthy tissues in the body.
Causes
Major histocompatibility complex class I deficiency is caused by mutations in genes that are involved in the production of MHC class I molecules. These mutations can result in a complete or partial absence of MHC class I molecules on the surface of cells. As a result, the immune system is unable to recognize and eliminate foreign invaders effectively.
Diagnosis
Major histocompatibility complex class I deficiency is diagnosed through a combination of clinical evaluation, genetic testing, and laboratory tests. Doctors may conduct blood tests to measure the levels of different immune cells and antibodies in the body. Genetic testing can also be used to identify mutations in genes associated with MHC class I deficiency.
Treatment
Currently, there is no cure for major histocompatibility complex class I deficiency. Treatment focuses on managing the symptoms of infections and providing supportive care. Antibiotics and antifungal medications may be used to treat infections, while immunoglobulin replacement therapy may be used to boost the immune system.
- Major histocompatibility complex class I deficiency is a rare genetic condition that affects the immune system.
- Individuals with this condition may experience recurrent infections and autoimmune disorders.
- The condition is caused by mutations in genes that are involved in the production of MHC class I molecules.
- Diagnosis is made through genetic testing and laboratory tests.
- Currently, there is no cure for major histocompatibility complex class I deficiency, and treatment focuses on managing symptoms.
Individuals with major histocompatibility complex class I deficiency may benefit from working with a team of healthcare professionals, including immunologists, infectious disease specialists, and genetic counselors. These professionals can provide specialized care and support to help manage

Treatment Options for Major Histocompatibility Complex Class I Deficiency
Major Histocompatibility Complex Class I Deficiency (MHC class I deficiency) is a rare genetic disorder that affects the immune system's ability to recognize and destroy infected or abnormal cells. People with MHC class I deficiency are at increased risk of developing severe and recurrent infections, as well ...
