Nephrotic syndrome is not a usual manifestation of BKV nephropathy. Here, we report a 12-year-old boy, a case of end-stage renal disease due to nephronophthisis, who got the kidney trans-planted from a 16-year-old cadaver, and after 18 months of uneventful transplantation on triple immunosuppressive therapy (Mycophenolate mofetil (MMF), cyclosporin and prednisolone), pre-sented with nephrotic feature (edema, heavy proteinuria, hypoalbuminemia and hyperlipidema). Kidney biopsy was in favor of BKV infection and eventually ended in graft failure. %U http://www.sjkdt.org/article.asp?issn=1319-2442;year=2011;volume=22;issue=1;spage=123;epage=125;aulast=Derakhshan
