The disease is caused by mutations affecting the gene represented in this entry. Most affected individuals have defects in methylation of the gene. In some cases microdeletions involving the STX16 appear to cause loss of methylation at exon A/B of GNAS, resulting in PHP1B. Paternal uniparental isodisomy have also been observed.

Function GNAS2_HUMAN Guanine nucleotide-binding proteins (G proteins) function as transducers in numerous signaling pathways controlled by G protein-coupled receptors (GPCRs) (PubMed:17110384). Signaling involves the activation of adenylyl cyclases, resulting in increased levels of the signaling molecule cAMP (PubMed:26206488, PubMed:8702665). GNAS functions downstream of several GPCRs, including beta-adrenergic receptors (PubMed:21488135). Stimulates the Ras signaling pathway via RAPGEF2 (PubMed:12391161). Publication Abstract from PubMed The beta(3)-adrenergic receptor (beta(3)AR) is predominantly expressed in adipose tissue and urinary bladder and has emerged as an attractive drug target for the treatment of type 2 diabetes, obesity, and overactive bladder (OAB). Here, we report the cryogenic electron microscopy structure of the beta(3)AR-G(s) signaling complex with the selective agonist mirabegron, a first-in-class drug for OAB. Comparison of this structure with the previously reported beta(1)AR and beta(2)AR structures reveals a receptor activation mechanism upon mirabegron binding to the orthosteric site. Notably, the narrower exosite in beta(3)AR creates a perpendicular pocket for mirabegron. Mutational analyses suggest that a combination of both the exosite shape and the amino-acid-residue substitutions defines the drug selectivity of the betaAR agonists. Our findings provide a molecular basis for betaAR subtype selectivity, allowing the design of more-selective agents with fewer adverse effects. Cryo-EM structure of the beta3-adrenergic receptor reveals the molecular basis of subtype selectivity.,Nagiri C, Kobayashi K, Tomita A, Kato M, Kobayashi K, Yamashita K, Nishizawa T, Inoue A, Shihoya W, Nureki O Mol Cell. 2021 Aug 5;81(15):3205-3215.e5. doi: 10.1016/j.molcel.2021.06.024.
