Genes affected

C1R (HGNC:1246): (complement C1r) This gene encodes a member of the peptidase S1 protein family. The encoded protein is a proteolytic subunit in the complement system C1 complex. The complement system acts as a mediator in the innate immune response by ultimately triggering phagocytosis, inflammation, and rupturing the bacterial cell wall. Mutations in this gene are associated with Ehlers-Danlos Syndrome. [provided by RefSeq, Dec 2018]

C1R links:

C1RL (HGNC:21265): (complement C1r subcomponent like) Predicted to enable serine-type endopeptidase activity. Predicted to be involved in zymogen activation. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]
