Summaries for Complement Component 7 Deficiency

UniProtKB/Swiss-Prot : 76 Complement component 7 deficiency: A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis.

MalaCards based summary : Complement Component 7 Deficiency, also known as c7 deficiency, is related to meningitis and meningococcal meningitis. An important gene associated with Complement Component 7 Deficiency is C7 (Complement C7). The drugs Trametinib and Durvalumab have been mentioned in the context of this disorder. Affiliated tissues include b cells and neutrophil, and related phenotypes are complement deficiency and recurrent meningococcal disease

Disease Ontology : 12 A complement deficiency that is characterized byrecurrnet bascterial infections, has material basis in mutation in the C7 gene.
