Also known as: FHR2; HFL3; CFHL2
Summary: This gene belongs to a family of complement factor H-related genes (CFHR), which are clustered together with complement factor H gene on chromosome 1, and are involved in regulation of complement. Mutations in CFHR genes have been associated with dense deposit disease and atypical haemolytic-uraemic syndrome. Alternatively spliced transcript variants have been found for this gene.

Title: CFHR2-rs2986127 as a genetic protective marker for acute anterior uveitis in Chinese patients.
Next-generation sequencing of the CFH region identified putatively functional variants (missense, splice site and indel) on the four common haplotypes. We found no expression of any of the five CFH-related genes in the retina or RPE/Choroid/Sclera, in contrast to the liver, which is the main source of the circulating proteins. [CFHR2]

Studies indicate that complement factor H-related proteins (FHR1-5) may enhance complement activation, with important implications for the role of these proteins in disease.

Thus CFHR2 likely acts in concert with factor H, as CFHR2 inhibits convertases while simultaneously allowing factor H assisted degradation by factor I.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
