Further important data regarding a predictive value of anti-nephrin autoantibodies were recently provided in a retrospective study by Batal et al., in which 38 kidney transplant recipients with the histological diagnosis of MCD or primary FSGS were investigated before transplantation (serum sample collection with a median of 4 days prior to transplantation) [8]. This evidence concerns the gene NPHS1 and focal segmental glomerulosclerosis.
