PTH, the main secretory product of parathyroid glands is responsible for regulation of calcium-phosphate homeostasis.\n\nObjective:\n\ni) To investigate the cause of parathyroid disorders\n\nii) To describe evolution, natural history, and longitudinal trends of parathyroid and related disorders seen in syndromic presentations like multiple endocrine neoplasia, hyperparathyroidism-jaw tumor syndrome\n\nEligibility:\n\nPeople ages 6 months older who have, are at risk of having, or are related to a person with a parathyroid or related disorder.\n\nDesign:\n\nParticipants will be screened with a review of their medical records.\n\nParticipants will be seen, tested, and treated by doctors based on their condition. Their visits may be in person or via telehealth.\n\nParticipants will complete questionnaires. They will answer questions about their physical, mental, and social health.\n\nParticipants may give samples such as saliva, blood, urine, or stool.\n\nParticipants may give cheek cell samples. They will do this using a cheek swab or by spitting into a cup.\n\nAdult participants may give a skin biopsy. For this, a small bit of skin is removed with a punch tool.\n\nParticipants may have medical photos taken.\n\nIf participants have surgery during the course of their regular care either at the NIH\n\nor at a different hospital or doctor s office, researchers will ask for some of the leftover\n\ntissue.\n\nParticipants will be in the study as long as they are being seen by their doctor.",[24,25,26,27,28],"Parathyroid Cancer","Primary Hyperparathyroidism","Pseudohypoparathyroidism","Inheritable Bone Diseases","Multiple Endocrine Neoplasia, Type 1",[30,31,24,32,33,34],"Hyperparathyroidism","calcium disorders","Inheritable","PSEUDOHYPOPARATHYROIDISM","Natural History","RECRUITING","2026-06-19",{"date":38,"type":39},"2026-06-23","ACTUAL",{"date":41,"type":39},"2021-11-30",{"date":43,"type":20},"2031-01-22",{"name":45,"class":46},"National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)","NIH"]
