The clinical condition resulting from end-organ resistance to parathormone (rPTH), caused by (epi)genetic alterations of GNAS, was termed as Pseudohypoparathyroidism (PHP). The high phenotype heterogeneity, the existence of additional clinical features such as resistance to other hormones (TSH/GHRH/gonadotropins) and Albright’s hereditary osteodystrophy (AHO), led to the distinction of specific PHP subtypes.The purpose of the present work is to prov...

Background: Disorders caused by impairments in the parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and the results of an in vitro as...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities that share a common PTH/PTHrP signaling pathway. The clinical and molecular overlap of PHP and related disorders lead to difficulties in clinical and molecular diagnosis which prompt to the possibility of incorrect management of these patients. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseou...
