Involvement in diseasei

Defects in CFHR5 have been found in patients with atypical hemolytic uremic syndrome and may contribute to the disease. Atypical hemolytic uremic syndrome is a complex genetic disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal failure and absence of episodes of enterocolitis and diarrhea. In contrast to typical hemolytic uremic syndrome, atypical forms have a poorer prognosis, with higher death rates and frequent progression to end-stage renal disease. Susceptibility to the development of atypical hemolytic uremic syndrome can be conferred by mutations in various components of or regulatory factors in the complement cascade system. Other genes may play a role in modifying the phenotype.
CFHR5 deficiency (CFHR5D) [MIM:614809]: A progressive disease characterized by glomerulonephritis, hematuria, renal failure, end-stage renal disease, subendothelial and mesangial glomerular C3 deposits, mesangial matrix expansion, increased glomerular cellularity, and segmental capillary wall thickening. Hematuria may become apparent after respiratory infections.
Note: The disease is caused by mutations affecting the gene represented in this entry.2 Publications
