The parathyroid glands are endocrine organs that play a key role in regulating calcium levels in the body by releasing parathyroid hormone (PTH), which acts on the bone, kidney, and small intestine.[1, 2] The glands consist of chief cells, which control the level of calcium ions in the bloodstream by secreting PTH, and oxyphil cells, whose function is not clearly determined.[3] Defects in parathyroid gland function, such as hyperparathyroidism or hypoparathyroidism, disrupt the calcium homeostasis and may potentially necessitate surgical treatment of parathyroid glands. This evidence concerns the gene PTH and hyperparathyroidism.
