According to a report, Asn is not glycosylated PubMed: Familial haemolytic uraemic syndrome. This mutation is referred to as glu to ter EX based on numbering that includes the initiation codon and signal peptide. A complement receptor locus: Looking For More References?

Complement factor H binds malondialdehyde epitopes and protects from oxidative stress. A radiation hybrid map of complement factor H and factor H-related genes. Complement regulation at necrotic cell lesions is impaired by the age-related macular degeneration-associated factor-H His risk allele. Addition of patient serum containing mutant factor H to control platelets resulted in cfy activation, deposition of C3 and C9, release of platelet-derived microparticles, and platelet aggregation, indicating platelet activation.
Human complement factor H deficiency associated with hemolytic uremic syndrome. The mutant CFH proteins showed a normal cofactor activity in the proteolysis of fluid-phase C3b by factor I, but demonstrated very low binding to surface-bound C3b.
The effect of this was to replace the last 7 amino acids of the protein with 3 different amino acids. It is associated with a number of renal diseases with variable clinical presentation and progression, including membranoproliferative glomerulonephritis and atypical hemolytic uremic syndrome.

Mutation analysis indicated that the region is involved in C3b binding. Please join your fch by making a donation now and again in the future. Structure of complement factor H carboxyl-terminus reveals molecular basis of atypical haemolytic uremic syndrome. In vitro studies showed that the EX mutant exhibited decreased binding to normal platelets compared to wildtype factor H. No signs of a renal disorder suggesting atypical hemolytic uremic syndrome or type II membranoproliferative glomerulonephritis were found in these patients.
Most aHUS-associated mutations either destabilize the structure or cluster in a unique region on the surface of domain Complement factor H polymorphism in age-related macular degeneration. In addition, Caprioli et al. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.

Journal of Immunological Methods. The Journal of Experimental Medicine. The mutation was not found in the father of the patient; the mother had died of postpartum HUS. A multiplicative model fitted the data well, and they estimated the population frequency of the high-risk C allele to be 0. Disease description A disorder that can manifest as several different phenotypes, including asymptomatic, recurrent bacterial infections, and renal failure.

It was characterized in human plasma and found to have factor H complement regulatory activity and cell ccfh activity.
Orphanet; a database dedicated to information on rare diseases and orphan drugs More Underactive factor H may result in increased complement activity on healthy host cells – resulting in autoimmune diseases. Genetic polymorphism of human factor H betaH Homozygous mutation of this gene results in markedly reduced serum C3, abnormal renal histology, spontaneous membranoproliferative glomerulonephritis MPGNhematuria, proteinuria, and increased mortality at 8 months of age.
In a case-control study of 1, unrelated affected individuals with advanced ARMD and controls, Maller et al. Pathogens that have been shown to recruit factor H include: Affected animals had excessive complement activation, massive deposits of complement in the renal glomeruli, and died cch renal failure within 11 weeks birth. Each of the CCP modules consists ch around 60 amino acids cfu four cysteine residues disulfide bonded in a arrangement, and a hydrophobic core built around an almost invariant tryptophan residue.
