From NCBI Gene:
This gene encodes the final component of the complement system. It participates in the formation of the Membrane Attack Complex (MAC). The MAC assembles on bacterial membranes to form a pore, permitting disruption of bacterial membrane organization. Mutations in this gene cause component C9 deficiency. [provided by RefSeq, Feb 2009]
Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells (PubMed:9634479, PubMed:9212048, PubMed:26841934). C9 is the pore-forming subunit of the MAC (PubMed:4055801, PubMed:26841934).

- Macular degeneration, age-related, 15
- Complement component 9 deficiency
Complement component 9 deficiency (C9D): A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections predominantly by Neisseria gonorrhoeae or Neisseria meningitidis. Some patients may develop dermatomyositis. [MIM:613825]
Macular degeneration, age-related, 15 (ARMD15): A form of age-related macular degeneration, a multifactorial eye disease and the most common cause of irreversible vision loss in the developed world. In most patients, the disease is manifest as ophthalmoscopically visible yellowish accumulations of protein and lipid that lie beneath the retinal pigment epithelium and within an elastin-containing structure known as Bruch membrane.
