C3 glomerulonephritis

A histological subtype of C3 glomerulopathy characterized by C3 deposition in renal tissue in the absence or near-absence of immunoglobulin deposits, in a patient with the classic clinical features of glomerulonephritis and the electron microscopic findings of predominant subendothelial, occasionally subepithelial (so-called ''humps''), and intramembranous deposits, but without the typical electron-dense deposits of dense deposit disease.
