Summaries for Pseudohypoparathyroidism, Type Ic

About this section
GARD : 20 Pseudohypoparathyroidism type 1C is a genetic disorder that is very similar to hypoparathyroidism (parathyroid hormone levels are too low). However, pseudohypoparathyroidism is caused by no response to parathyroid hormone rather than having too little of the hormone itself. This causes low calcium and high phosphate levels in the blood. This condition is also associated with a group of symptoms referred to as Albright's hereditary osteodystrophy, which includes short stature, a round face, obesity, and short hand bones. This disorder is different than pseudohypoparathyroidism type 1A because people with type 1C do not have abnormal activity of a particular protein (stimulatory protein G (Gs alpha)). Type 1C is inherited in an autosomal dominant fashion and is caused by a specific spelling mistake (mutation) in the GNAS gene.

MalaCards based summary : Pseudohypoparathyroidism, Type Ic, also known as pseudohypoparathyroidism type 1c, is related to pseudohypoparathyroidism and pseudohypoparathyroidism, type ia, and has symptoms including seizures An important gene associated with Pseudohypoparathyroidism, Type Ic is GNAS (GNAS Complex Locus), and among its related pathways/superpathways is G alpha (s) signalling events. Affiliated tissues include eye, bone and thyroid, and related phenotypes are pseudohypoparathyroidism and hyperphosphatemia

OMIM® : 57 Pseudohypoparathyroidism type Ic (PHP1C) is characterized by resistance to parathyroid hormone (PTH; 168450) as well as to other hormones. It is associated with a constellation of physical features referred to as Albright hereditary osteodystrophy (AHO), which includes short stature, obesity, round facies, subcutaneous ossifications, brachydactyly, and other skeletal anomalies. Some patients have mental retardation. Laboratory studies in patients with PHP Ic show a decreased cellular cyclic AMP (cAMP) response to infused PTH, but no defect in activity of the erythrocyte Gs protein (Mantovani and Spada, 2006). (612462) (Updated 05-Mar-2021)

UniProtKB/Swiss-Prot : 73 Pseudohypoparathyroidism 1C: A disorder characterized by end-organ resistance to parathyroid hormone, hypocalcemia and hyperphosphatemia. It is commonly associated with Albright hereditary osteodystrophy whose features are short stature, obesity, round facies, short metacarpals and ectopic calcification.
