In our patient we found two polymorphisms already known as pathogenic for C3GN in CFH (p.V62I in SCR1) and THBD (p.A473V) genes, as well as a polymorphism so far associated to age-related macular degeneration (AMD) in C3 (p.R102G) [13]. This evidence concerns the gene THBD and age-related macular degeneration.
