What is the official name of the CFHR5 gene?
The official name of this gene is “complement factor H-related 5.”
CFHR5 is the gene's official symbol. The CFHR5 gene is also known by other names, listed below.

What is the normal function of the CFHR5 gene?
The CFHR5 gene provides instructions for making a protein called complement factor H-related 5. The precise function of this protein is unknown. However, its structure is similar to that of a protein called complement factor H (which is produced from the CFH gene). This similarity provides clues to the probable function of complement factor H-related 5.
Complement factor H regulates a part of the body's immune response known as the complement system. The complement system is a group of proteins that work together to destroy foreign invaders (such as bacteria and viruses), trigger inflammation, and remove debris from cells and tissues. This system must be carefully regulated so it targets only unwanted materials and does not attack the body's healthy cells. Complement factor H helps to protect healthy cells by preventing activation of the complement system when it is not needed. Studies suggest that complement factor H-related 5 probably plays a related role in controlling the complement system.
Does the CFHR5 gene share characteristics with other genes?
The CFHR5 gene belongs to a family of genes called complement (complement system).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
