PMID: 26283675 - Bu et al 2016 - screened 193 patients using a gene panel facilitate genetic testing in aHUS, TTP, C3GN, and DDD. Report 1 variant found in a patient with aHUS and 3 in patients with C3 glomerulonephritis. Individual patient and variant information not given.

PMID: 25758434 - Imamura et al 2015 - 1 family. Daughter diagnosed with C3 glomerulonephritis, mother treated for membranoproliferative glomerulonephritis, and brother with hypocomplementemia without urinary abnormalities. All 3 found to have heterozygosity for CFB p.S367R that was not present in the unaffected father or younger sister. Other variants were found in the daughter, CFI p.R201S and C3 p.V916I were excluded as in other unaffected individuals or appear in high frequency in other populations. They propose that it is highly likely that p.S367R causes a gain of function in CFB through a structure–function relationship.

Membranoproliferative glomerulonephritis including C3 glomerulopathy v1.6 C3 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.
