Genes affected

CFHR3 (HGNC:16980): (complement factor H related 3) The protein encoded by this gene is a secreted protein, which belongs to the complement factor H-related protein family. It binds to heparin, and may be involved in complement regulation. Mutations in this gene are associated with decreased risk of age-related macular degeneration, and with an increased risk of atypical hemolytic-uremic syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

CFHR3 Gene-Disease associations (from GenCC):

• hemolytic uremic syndrome, atypical, susceptibility to, 1
