Fibronectin nephropathy has all of the following features except:: (A) Autosomal recessive inheritance, (B) Associated with mesangial expansion, (C) Glomeruli do not stain for immunoglobulin or complement, (D) PAS- positive amyloid negative deposits.
Answer is A. Fibronectin nephropathy Autosomal dominant mode Proteinuria (MC presentation) and slowly progressive loss of renal function. Serum Fibronectinlevels are normal. Light microscopy: Glomerular enlargement and PAS ([?]), trichrome-positive but amyloid (-) mesangial deposits. Electron microscopy: Large (giant), mesangialand subendothelial electron-dense deposits.
