Genes affected

CFH (HGNC:4883): (complement factor H) This gene is a member of the Regulator of Complement Activation (RCA) gene cluster and encodes a protein with twenty short consensus repeat (SCR) domains. This protein is secreted into the bloodstream and has an essential role in the regulation of complement activation, restricting this innate defense mechanism to microbial infections. Mutations in this gene have been associated with hemolytic-uremic syndrome (HUS) and chronic hypocomplementemic nephropathy. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Oct 2011]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on CFH function (PMID: 34189567, 36445700). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 157562). This missense change has been observed in individual(s) with pneumonia, age-related macular degeneration or atypical hemolytic uremic syndrome (PMID: 24906858, 26501415, 29888403, 30295827, 32185379, 34508573, 35930268). This variant is present in population databases (rs570523689, gnomAD 0.004%). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 503 of the CFH protein (p.Pro503Ala). -
