Eleanor Williams edited their review of gene: CFI: Added comment: Only renal phenotype in OMIM this gene is associated with is {Hemolytic uremic syndrome, atypical, susceptibility to, 3} 612923. Papers cited by the BRIDGE consortium PMID: 18371543 - Boyer et al 2008 - Patient 1 with atypical hemolytic and uremic syndrome had combined CFH and CFI heterozygous mutations. PMID: 22456601 - Servais et al 2012 - for 141 patients from 45 centers with a definite diagnosis of primary MPGN I, DDD, or GNC3 they performed direct sequencing of CFH, CFI, or MCP exons and of a set of 10 SNPs within the CFH and MCP genes. 6 patients had heterozygous variants in CFI, 3 of which are reported in patients with MPGN histology (Table 2). Following expert review rating this gene Red, and review of the literature this gene should be down graded to Amber or Red.; Changed rating: RED |

Eleanor Williams commented on gene: C3: Associated with C3 deficiency (#613779) and {Hemolytic uremic syndrome, atypical, susceptibility to, 5} (#612925) in OMIM. PMID: 20852386 - Martínez-Barricarte et al 2010 - report a case a mother and her two identical twin sons with Dense deposit disease (DDD) caused by a heterozygous variant in the C3 gene. The mutation, c.2767_2774delACGGTG (C3923ΔDG) in exon 21, results in a mutated protein (C3923ΔDG) lacking 2 amino acids (Asp923 and Gly924) in the MG7 domain of C3. The deletion was only present in affected family members. Functional studies suggest a gain of function. PMID: 26471127 - Chauvet et al 2016 - report functional characterization of a C3 mutation identified in two brothers with C3GN (C3 glomerulopathy). Both carry the same c.2327T>C heterozygous mutation in the C3 gene, leading to p.I756T. The mutation was not found in the 1000 genomes or EVS databases. In vitro the C3 mutation exhibited decreased binding to CR1, resulting in less CR1-dependent cleavage of C3b by factor 1. |
