People with Barakat syndrome, a neuromuscular disorder with clinical diversity characterized by hypoparathyroidism, sensorineural deafness and renal disease, usually present with hypocalcaemia, tetany, or afebrile convulsions at any age.
It is a genetic developmental disorder with clinical diversity characterized by hypoparathyroidism, sensorineural deafness and renal disease. Hypoparathyroidism is decreased function of the parathyroid glands with underproduction of parathyroid hormone. Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures) or the vestibulocochlear nerve (cranial nerve VIII). Affected people usually present with hypocalcaemia, tetany, or afebrile convulsions at any age. Hypocalcaemia is low calcium levels in the blood serum.
