Activating GNAS (R201C) mutations were found in 2 unrelated patients with virilizing ovarian Leydig cell tumors. This mutation and subsequent cAMP increase may play a significant role in the pathogenesis of virilizing LCT through the stimulation of androgen production and tumor development.
mutation analysis of GNAS by pyrosequencing has diagnostic value in FFPE tissue of patients with FD, especially in specimens that were not decalcified. The R201H substitution mutation of GNAS may be involved in the pathogenesis of polyostotic FD.
GNAS mutations can be used as good diagnostic tool to distinguish intramuscular / cellular myxoma from low-grade myxofibrosarcoma, especially on biopsy material.
GNAS T/C 393 frequencies were similar in control and PHPT groups. No association was found between genotypes and clinical expression of PHPT. A nonstatistically significant trend was seen to lower BMD in the lumbar spine, femoral neck, and total hip in both PHPT and control C homozygote subjects. A C allele-related susceptibility to lower BMD in trabecular bone in both groups is not enough to suggest more severity.

Low Gs-alpha expression is associated with obesity with increased food intake and decreased energy expenditure, along with impaired insulin sensitivity and cold-induced thermogenesis.
In mice that express activated KRAS in the pancreas, we found expression of GNAS(R201C) to cause development of more differentiated tumors, with gene expression pattern associated with the ductal phenotype.

This study demonstrates that induced expression of the fibrous dysplasia (FD) Galphas mutant from the mouse endogenous Gnas locus exhibits human FD phenotypes in vivo, and that inhibitors of Wnt/beta-catenin signaling may be repurposed for treating FD and other bone diseases caused by Galphas activation.
high osteoblastic GalphaS expression results in aberrant skeletal development in which bone production is favored at the cost of bone quality.

Our data revealed a positive correlation between hepatic Gsalpha-cAMP signal axis and fasting blood glucose (FBG) in slight insulin resistance stage of HIgh Sugar High Fat-diet rats and diabetic db/db mice. The current finding thus suggested hepatic Gsalpha-cAMP signal axis plays a central role in regulating of FBG during the developing and development of T2DM.

This locus has a highly complex imprinted expression pattern. It gives rise to maternally, paternally, and biallelically expressed transcripts that are derived from four alternative promoters and 5' exons. Some transcripts contain a differentially methylated region (DMR) at their 5' exons, and this DMR is commonly found in imprinted genes and correlates with transcript expression. An antisense transcript is produced from an overlapping locus on the opposite strand. One of the transcripts produced from this locus, and the antisense transcript, are paternally expressed noncoding RNAs, and may regulate imprinting in this region. In addition, one of the transcripts contains a second overlapping ORF, which encodes a structurally unrelated protein - Alex. Alternative splicing of downstream exons is also observed, which results in different forms of the stimulatory G-protein alpha subunit, a key element of the classical signal transduction pathway linking receptor-ligand interactions with the activation of adenylyl cyclase and a variety of cellular reponses. Multiple transcript variants encoding different isoforms have been found for this gene. Mutations in this gene result in pseudohypoparathyroidism type 1a, pseudohypoparathyroidism type 1b, Albright hereditary osteodystrophy, pseudopseudohypoparathyroidism, McCune-Albright syndrome, progressive osseus heteroplasia, polyostotic fibrous dysplasia of bone, and some pituitary tumors.
