Other specified defects in the complement system are caused by genetic mutations that alter the proteins that comprise the complement system. These mutations can cause a decreased or increased activity of the proteins and can prevent the proper functioning of the complement system.
Diagnosis of other specified defects in the complement system is typically done through blood tests that look for levels of the complement proteins. Genetic testing may also be done to identify the specific mutation causing the defect.
Differential diagnosis for other specified defects in the complement system includes other genetic disorders that can affect the complement system, such as C3 deficiency, C4 deficiency, and Factor I deficiency.
Treatment of other specified defects in the complement system typically involves replacing the deficient proteins with intravenous infusions of the proteins or by providing oral medications that can increase the activity of the deficient proteins.
The prognosis of other specified defects in the complement system is typically good, as long as the patient is able to adhere to the prescribed treatment regimen. With proper treatment, the patient should be able to lead a normal and healthy life.
