Abstract

Hypocalcemia is a common electrolyte disturbance with a variety of causes. Hypoparathyroidism, sensorineural deafness, and renal disease (HDR) syndrome is a rare autosomal-dominant genetic disorder characterized by hypoparathyroidism, sensorineural deafness, and renal disease. This is a case presentation of HDR syndrome that had been referred to a hospital with hypocalcemia. This case has a unique feature as it has been diagnosed in adult age because usually HDR syndrome is diagnosed in pediatric age group.
