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]

The c.565G>A (p.E189K) alteration is located in exon 5 (coding exon 5) of the CFH gene. This alteration results from a G to A substitution at nucleotide position 565, causing the glutamic acid (E) at amino acid position 189 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 189 of the CFH protein (p.Glu189Lys). This variant is present in population databases (rs121913054, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CFH-related conditions. ClinVar contains an entry for this variant (Variation ID: 1355349). 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. 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. -
