Involvement in diseasei

Pseudohypoparathyroidism 1B (PHP1B)2 Publications
The gene represented in this entry is involved in disease pathogenesis. Microdeletions involving STX16 can cause loss of methylation at exon A/B of GNAS, resulting in PHP1B.
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.
