Three patients developed Wilms tumor, and three phenotypic females had a 46,XY karyotype with gonadal dysgenesis. Twelve distinct WT1 variants were identified, predominantly exon 9 missense variants and intron 9\u201310 splice-site variants. After a median follow-up of 32 months, all grafts remained functional, with a median estimated glomerular filtration rate of 68.7 mL\/min\/1.73 m\u00b2. Epstein\u2013Barr virus viremia occurred in five patients, and two developed post-transplant lymphoproliferative disorder. No disease recurrence was observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Kidney transplantation achieved favorable short- to mid-term graft outcomes in this cohort.
