Genes affected
CFHR5 (HGNC:24668): (complement factor H related 5) This gene is a member of a small complement factor H (CFH) gene cluster on chromosome 1. Each member of this gene family contains multiple short consensus repeats (SCRs) typical of regulators of complement activation. The protein encoded by this gene has nine SCRs with the first two repeats having heparin binding properties, a region within repeats 5-7 having heparin binding and C reactive protein binding properties, and the C-terminal repeats being similar to a complement component 3 b (C3b) binding domain. This protein co-localizes with C3, binds C3b in a dose-dependent manner, and is recruited to tissues damaged by C-reactive protein. Allelic variations in this gene have been associated, but not causally linked, with two different forms of kidney disease: membranoproliferative glomerulonephritis type II (MPGNII) and hemolytic uraemic syndrome (HUS).

Variant summary: CFHR5 c.678delA (p.Glu226AspfsX7) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, however current evidence is not sufficient to establish loss of function as a mechanism for disease. The variant allele was found at a frequency of 8e-06 in 251136 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.678delA has been reported in the literature in at least one individual affected with atypical hemolytic uremic syndrome and one individual with C3 glomerulopathy (e.g., Rydberg_2023). Both individuals also carried other variants in CFHR5 as well as variants in other genes associated with kidney disease. This variant has also been reported in at least one individual with infertility (e.g., Dougherty_2023). These report(s) do not provide unequivocal conclusions about association of the variant with CFHR5 Deficiency. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 36920765, 37744338). ClinVar contains an entry for this variant (Variation ID: 226110). Based on the evidence outlined above, the variant was classified as uncertain significance. -
