Familial idiopathic hypoparathyroidism, sensorineural deafness and renal dysplasia

We describe a 27-year-old woman with familial idiopathic hypoparathyroidism, bilateral sensorineural deafness and right renal aplasia, There was a family history of deafness in her father and two other family members with sensorineural deafness, one of whom had hypoparathyroidism, To our knowledge, there have been four previous reports of idiopathic hypoparathyroidism associated with sensorineural deafness and renal dysplasia, The clinical features were not identical to any of the four previous reports. Although no chromosome abnormalities were present in the patient using standard trypsin G-handing analysis, we speculate that some common genetic mutation caused hypoparathyroidism, sensorineural deafness and renal dysplasia.
