The Prevalence of GNAS Deficiency-Related Diseases in a Large Cohort of Patients Characterized by the EuroPHP Network

Abstract: With European data, we have established the prevalence of various genetic and epigenetic lesions in PHP-affected patients. Using these findings, we will develop objective criteria to guide cost-effective strategies for genetic testing and explore the implications for management and prognosis.

“…The overlap between the diseases ( Table 1 and Supplementary Table 1) renders the diagnosis complex and the classification inadaptable and obsolete. In addition, the tools to investigate patients have evolved, measurement of G s α activity in cell membranes is not readily available and molecular genetic diagnosis has become the gold standard by which PHP variants are distinguished 17 . Recommendations 1.13.…”

“…A molecular cause can be identified in an estimated 80-90% of patients with PHP or related disorders 16,17 . The most common underlying mechanisms are de novo or autosomal dominantly inherited genetic mutations and/or epigenetic, sporadic or genetic-based alterations, within or upstream of GNAS 4,18,19 , PRKAR1A 6 , PDE4D 5,20 or PDE3A 21 ( Fig.…”

“…More than 170 germline mutations in the GNAS coding region have been identified in patients with PHP1a, pseudo-PHP, or other related conditions [Lemos and Thakker, 2015;Elli et al, 2016;Thiele et al, 2016]. A substantial percentage of these mutations were found to be de novo abnormalities [Lemos and Thakker, 2015;.…”
