In clinical practice, we can now directly measure the level of circulating parathormone and we can also assess its impact on its renal effector by the assay of cyclic adenosine monophosphate. The radio-immunoassay of parathormone uses antisera with amino or carboxy terminal specificity. The
Parathyroid hormone (PTH) is essential for calcium homeostasis and its action is mediated by the PTH type 1 receptor (PTHR1), a class B G-protein-coupled receptor. Hypoparathyroidism and osteoporosis can be treated with PTH injections; however, no orally effective PTH analogue is available. Here we
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), also known as autoimmune polyglandular syndrome type I, is a rare autosomal recessively inherited disorder characterized by variable combinations of endocrine and nonendocrine symptoms. In this report, we describe two 20- and
DiGeorge syndrome (DGS) is a developmental field defect of the third and fourth pharyngeal pouches that are associated with congenital heart defects, hypoparathyroidism, cell-mediated immunodeficiency, velopharyngeal insufficiency, and craniofacial anomalities. Approximately 90% of patients exhibit
Autoimmune polyendocrine syndrome type 1 (APS-1, OMIM 2403000) is a rare autosomal recessive disease that is caused by autoimmune regulator (AIRE). The main symptoms of APS-1 are chronic mucocutaneous candidiasis, autoimmune adrenocortical insufficiency (Addison's disease) and hypoparathyroidism. We
Autosomal dominant hypocalcemia (ADH) caused by activating mutations of calcium-sensing receptor (CaSR) is characterized by hypocalcemia with inappropriately low concentration of PTH and relative hypercalciuria. Active vitamin D treatment often leads to nephrolithiasis and renal impairment in
The calcium-sensing receptor (Ca-R) is a G-protein-coupled surface receptor that plays a crucial role in calcium homeostasis via parathyroid hormone secretion. Mutations of this receptor can cause a gain in, or loss of, function, leading to hypo- or hypercalcemia, respectively. We report here a
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; OMIM *240300, also called APS 1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is generally characterized by two of the three major clinical symptoms that may be present,
