The rate of disease recurrence in patients with idiopathic membranous GN following kidney transplantation is between 30 and 50%, with the disparate detection rates reported in the studies influenced by the characteristics of the cohort (e.g., those with high titres of circulating anti-PLA2R autoantibody have a greater risk of recurrent disease), follow-up period and dissimilar biopsy practices (Table 1) (4, 158). This evidence concerns the gene PLA2R1 and idiopathic membranous glomerulonephritis.
