A genetic deficiency of any membrane attack complex (MAC, also known as terminal component complex (TCC)) component of the complement system (C5, C6, C7, C8, C9). Deficiencies of the terminal complement pathway results in a predisposition to infections, such as invasive meningococcal disease or disseminated gonococcal infection.
No clinical trials have been registered for immunodeficiency due to a late component of complement deficiency.
25 publications have been identified in PubMed for immunodeficiency due to a late component of complement deficiency. Research spans Basic Science / Preclinical (56%), Review / Meta-Analysis (16%), and Gene Therapy / Novel Therapeutics (12%).
