PHP1B -iPPSD3 per the new proposed classification- is a rare disorder characterized in most patients by proximal tubular resistance to PTH resulting in hypocalcemia, hyperphosphatemia and elevated PTH. Loss-of-methylation (LOM) at the Differentially Methylated Region (DMR) at GNAS exon A/B occurs in all PHP1B patients, but methylation changes at other DMRs within GNAS occur in some familial and most sporadic PHP1B cases. All patients with autosomal dominant PHP1B (AD-...

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...
