Involvement in diseasei

GNAS hyperfunction (GNASHYP)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionThis 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.

ACTH-independent macronodular adrenal hyperplasia 1 (AIMAH1)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA 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 truncal obesity, abdominal striae, muscular weakness, osteoporosis, arterial hypertension, diabetes.
See also OMIM:219080
Pseudohypoparathyroidism 1B (PHP1B)7 Publications
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.
Disease descriptionA disorder characterized by end-organ resistance to parathyroid hormone, hypocalcemia and hyperphosphatemia. Patients affected with PHP1B lack developmental defects characteristic of Albright hereditary osteodystrophy, and typically show no other endocrine abnormalities besides resistance to PTH.
See also OMIM:603233
Colorectal cancer (CRC)
The disease may be caused by mutations affecting the gene represented in this entry.
Disease descriptionA complex disease characterized by malignant lesions arising from the inner wall of the large intestine (the colon) and the rectum. Genetic alterations are often associated with progression from premalignant lesion (adenoma) to invasive adenocarcinoma. Risk factors for cancer of the colon and rectum include colon polyps, long-standing ulcerative colitis, and genetic family history.
