    Defects in GNAS are a cause of ACTH-independent macronodular adrenal hyperplasia (AIMAH); also known as adrenal Cushing syndrome due to AIMAH. A rare adrenal defect characterized by multiple, bilateral, non-pigmented, benign, adrenocortical nodules. It results in excessive production of cortisol leading to ACTH-independent Cushing syndrome. Clinical manifestations of Cushing syndrome include facial and trunkal obesity, abdominal striae, muscular weakness, osteoporosis, arterial hypertension, diabetes. Genetic variations in GNAS are the cause of pseudohypoparathyroidism type 1B (PHP1B). PHP1B is characterized by parathyroid hormone (PTH)-resistant hypocalcemia and hyperphosphatemia. Patients affected with PHP1B have normal activity of the product of GNAS, lack developmental defects characteristic of AHO, and typically show no other endocrine abnormalities besides resistance to PTH. 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. Defects in GNAS are the cause of GNAS hyperfunction (GNASHYP). This condition is characterized by increased trauma-related bleeding tendency, prolonged bleeding time, brachydactyly and mental retardation. Both the XLas isoforms and the ALEX protein are mutated which strongly reduces the interaction between them and this may allow unimpeded activation of the XLas isoforms.
