Living-donor kidney transplantation for a patient with hypoparathyroidism, deafness, and renal dysplasia syndrome.

Over intake of vitamin D caused nephrocalcinosis. The renal function was improved after living-donor kidney transplantation and the patient's serum calcium levels normalized without vitamin D supplementation. Therefore, kidney transplantation should be considered a treatment option for patients with hypoparathyroidism, sensorineural deafness, and renal dysplasia syndrome.
