These idiosyncratic cases highlight the lack of clear correlation between WT1 mutations and urogenital pathology, and intronic mutations have been reported with FS [3, 19], DDS, and isolated DMS [24] and various atypical presentations including FS with Wilms tumor [25] and 46,XX females with FSGS only [22, 26]. This evidence concerns the gene WT1 and Nephroblastoma.
