C21527	Complement C3	Complement C3	C3	Complement C3 (1663 aa, ~187 kDa) is encoded by the human C3 gene. This protein plays a role in complement-mediated immunity.

C70618	Complement Component-4	Complement C4	C4	Complement component-4 (1744 aa, ~193 kDa) is part of the complement cascade, which mediates the innate immune response to infection. The full length protein is a precursor that is secreted as a trimeric molecule containing an alpha, beta and gamma chain. When the complement cascade is initiated, the protein is cleaved. This proteolysis releases both the alpha chain, C4 anaphylatoxin, which stimulates inflammation, and a dimer of the beta and gamma chains, which mediates the interaction between the antigen-antibody complex and other complement components.	An early component of the classical and mannose binding lectin (MBL) complement activation pathways. C4 is consumed by proteolysis upon activation of the classical and MBL pathways, but not the alternative pathway. C4 levels are generally low in active immune complex diseases mediated by classical or MBL activation, but not alternative activation, with the canonical example being systemic lupus erythematosus.

C4691	Complement Deficiency	Complement Deficiency		A broad classification for rare genetic disorders with mostly autosomal recessive patterns of inheritance. They are caused by the ineffective or decreased biosynthesis of complement components. Complement deficiencies may also be acquired acutely post-infection or chronically from co-morbid autoimmune disorders. If complement components are adequately synthesized, their rapid depletion may result in functional deficiencies. Clinical signs of inherited deficiencies present within the first decade of life and are consistent with the signs of recurrent systemic infection or immune complex disease. Complement deficiencies decrease the effectiveness of the humoral immune response. Of all the complement deficiencies, C3 deficiency is associated with the poorest prognosis since it presents at an early age, when susceptibility to recurrent infection is great. Deficiencies of C3 and of the classical activating pathway components: C1, C4, C2 also predispose to immune complex disease.	A genetic deficiency of any component of the complement system, which may be associated with various pathologic conditions depending on the protein and activation pathway involved.
