GNAS Mutations in Pseudohypoparathyroidism Type 1a and Related Disorders
Pseudohypoparathyroidism type 1a (PHP1a) is characterized by hypocalcaemia and hyperphosphatemia due to parathyroid hormone resistance, in association with the features of Albright's hereditary osteodystrophy (AHO). PHP1a is caused by maternally inherited inactivating mutations of Gs-alpha, which is encoded by a complex imprinted locus termed GNAS. Paternally inherited mutations can lead either...

متن کاملPseudohypoparathyroidism type 1a due to a novel mutation in the GNAS gene
Dear Editor, Pseudohypoparathyroidism type 1a (PHP1a) (OMIM #103580) is characterized by hypocalcaemia and hyperphosphataemia due to parathyroid hormone (PTH) resistance, associated with features of Albright’s Hereditary Osteodystrophy (AHO) which include short stature, obesity, subcutaneous calcifications and brachydactyly. PHP1a is caused by heterozygous germline mutations of the alpha subuni...
متن کاملEctopic Calcification as Discernible Manifestation in Neonates with Pseudohypoparathyroidism Type 1a
The diagnosis of pseudohypoparathyroidism type 1a (PHP1a) is challenging, because both the osteodystrophy, such as brachydactyly and round face, and the symptomatic hypocalcemia usually develop beyond infancy. Although ectopic calcification may be an early sign of PHP1a, there are no systematic reviews regarding the time of its appearance. We here report on two PHP1a patients who presented with...
