Gene Type | protein-coding |
Organism | Homo sapiens(human) |
Genome | |
Summary | 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]. |

To our knowledge, this is the first evaluation of the involvement of the CFHR3/CFHR1 deletion and age-related macular degeneration in CFH Y402H polymorphism Brazilian patients.
Title: Evaluation of CFH Y402H polymorphism and CFHR3/CFHR1 deletion in age-related macular degeneration patients from Brazil.
Exploratory analyses of clinical and histopathologic parameters using the Oxford classification criteria revealed a suggestive association of CFHR3,1Delta with reduced tubulointerstitial injury. These data indicate that dysregulated activity of the alternative complement pathway contributes to IgAN pathogenesis in both Asians and Europeans and implicate CFHR3,1Delta as the functional allele at this locus

These data provide evidence that FHR3, which is absent in patients with the autoimmune form of hemolytic uremic syndrome, is involved in B cell regulation
Title: FHR3 Blocks C3d-Mediated Coactivation of Human B Cells.
We describe a novel CFH/CFHR3 hybrid gene secondary to a de novo 6.3-kb deletion that arose through microhomology-mediated end joining rather than nonallelic homologous recombination. We confirmed a transcript from this hybrid gene and showed a secreted protein product that lacks the recognition domain of factor H and exhibits impaired cell surface complement regulation

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.[CFHR3]

The following CFHR3 gene cDNA ORF clone sequences were retrieved from the NCBI Reference Sequence Database (RefSeq). These sequences represent the protein coding region of the CFHR3 cDNA ORF which is encoded by the open reading frame (ORF) sequence. ORF sequences can be delivered in our standard vector, pcDNA3.1+/C-(K)DYK or the vector of your choice as an expression/transfection-ready ORF clone. Not the clone you want?
