Proteinuria is a common finding in clinical practice. Kidney diseases such as glomerulonephritis, tubule-interstitial nephritis are differential diagnoses that need to be ruled out. Fabry disease, a rarely seen X-linked hereditary disease, which is caused by an enzyme deficiency, leads to the accumulation of glycolipids, ensued by systemic symptoms. The kidney is the one among the affected vital organs, microalbuminuria or proteinuria may present at the early stage of Fabry nephropathy. Herein, we present a case involving Fabry nephropathy in a man with a presentation of proteinuria undergoing renal biopsy. The pathogenesis, clinical manifestations, associated biomarkers, pathologic features, treatment, and prognosis of Fabry disease and Fabry nephropathy were reviewed.
