Clinicopathological Characteristics and Outcomes of PLA2R-Associated Membranous Nephropathy in Seropositive Patients Without PLA2R Staining on Kidney Biopsy
Phospholipase A2 receptor (PLA2R)–associated membranous nephropathy (MN) with circulating serum autoantibodies to PLA2R (SAb+) but no deposits of PLA2R antigen in glomerular tissue by immunofluorescence (GAg−) has been reported. However, little is known about the clinicopathological characteristics or prognosis of this subtype of MN.
