Beyond the Usual Suspects: FAT1-Positive De Novo Membranous Nephropathy in a Kidney Transplant Recipient (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #FR-PO1160; Pres time: Oct 23, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "Induction immunosuppression included antithymocyte globulin and steroids with maintenance tacrolimus, mycophenolate mofetil and prednisone...He received steroids, IVIG, and rituximab with improvement in proteinuria and resolution of DQA1 but persistent DSA against DQ2...In this case, the persistent and rising DSA with rejection demonstrates a temporal association between alloimmune activity and the development of FAT1-associated MN, raising the possibility that the recipient developed intolerance to FAT1 antigen. Additionally, this case underscores the role of mass spectrometry in PLA2R-negative MN for antigen identification and disease characterization."
