Complement component C8, A chain
The C8A gene encodes the alpha subunit of the complement component 8. C8 participates in the formation of the membrane attack complex (MAC) which disrupts bacterial walls, which mediates cell lysis. Mutations cause autosomal recessive complement C8 deficiency type 1.
