该基因属于补体因子H相关基因家族（CFHR），与1号染色体上的补体因子H基因簇合在一起，参与补体的调控CFHR基因突变与致密沉积病和非典型溶血性尿毒综合征有关另外，已经发现该基因的剪接转录变体。[由RefSeq提供，2015年8月]
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.
