Renal Transplant in a Bardet-Biedl Syndrome Patient: A First Case From Azerbaijan.

Introduction: Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy characterized by multisystem involvement, with renal pathology, including end-stage renal disease, being a major cause of morbidity and mortality. Case Presentation: This case report presents a 14-year-old boy with BBS and end-stage renal disease who underwent a successful living donor kidney transplantation, marking the first reported case in Azerbaijan. Despite multiple comorbidities, including obesity, hypertension, and high panel reactive antibody levels, the patient achieved stable graft function with a rapid postoperative creatinine decline. Postoperative management focused on immunosuppression and lifestyle adjustments. Conclusion: This case contributes to the limited literature on BBS, highlighting both the challenges and favorable outcomes of renal transplantation in patients with this rare genetic disorder.
