Association of a novel complement factor H mutation with severe crescentic and necrotizing glomerulonephritis.

ABSTRACT: Severe crescentic and necrotizing glomerulonephritis typically is associated with anti-glomerular basement membrane or antineutrophil cytoplasmic antibodies. In this report, we describe a 23-year-old man with severe crescentic and necrotizing glomerulonephritis. Both anti-glomerular basement membrane and antineutrophil cytoplasmic antibody titers were negative. Kidney biopsy showed bright C3 staining in the mesangium and along capillary walls and no staining for immunoglobulins. Electron microscopy showed waxy deposits (many mesangial; few intramembranous or subendothelial), prompting evaluation of the alternative pathway of complement. Alternative pathway evaluation showed a novel mutation in short consensus repeat (SCR) 19 of complement factor H. In addition, the patient carried compleme
