{Abstract}: Fibrillary glomerulonephritis (FGN) is a rare glomerular disorder characterized by the deposition of randomly arranged fibrils in the mesangium and the glomerular basement membrane. Clinical features include massive albuminuria, hematuria, high blood pressure, and kidney failure. Usually, the renal prognosis is not favorable, with evolution to end-stage renal disease in approximately 50% of cases. Recent studies in proteomics have identified a member of the heat shock protein family, also called DNAJB9, which is deposited in the glomerulus of patients with FGN and is not present in other diseases, such as amyloidosis or immunotactoid glomerulopathy. These findings are the first step to clarify the pathogenesis of this disease and could facilitate its diagnosis. Hence, we present a case of FGN with mild albuminuria at baseline and discuss the usefulness of this novel biomarker for diagnosing this group of patients.
