Old terminology	Examples of new more specific terminology
Idiopathic membranous nephropathy	Membranous nephropathy due to PLA2R antibodies
MPGN	C3 glomerulonephritis secondary to factor I deficiency
Idiopathic FSGS	Genetic FSGS due to nephrin deficiency
ANCA vasculitis	Anti-PR3 granulomatosis with polyangiitis
