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]

Variant summary: CFH c.3572C>T (p.Ser1191Leu) results in a non-conservative amino acid change located in the last (i.e. the C-terminal) sushi/SCR/CCP repeat domain (IPR000436) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 251154 control chromosomes (gnomAD v2.1). The variant, c.3572C>T, has been reported in the literature in several individuals (see HGMD, OMIM), who were affected with atypical hemolytic uremic syndrome (aHUS); notably, in a proportion of the reported cases this variant occurred in combination with Val1197Ala (including 2 proven de novo cases), as a result of a gene conversion event (see Heinen_2006). Publications reported experimental evidence evaluating an impact on protein function, and demonstrated that the variant in isolation resulted in defects of activities characteristic for the functions of C-terminal region of the protein (Heinen_2006, Merinero_2021). Of note, the variant in combination (i.e. in cis) with Val1197Ala also was associated with a defective function (Heinen_2006). One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
