hypoparathyroidism (lowered levels of parathyroid hormone), but is caused by a lack of response to parathyroid hormone rather than having too little of the hormone itself. This condition is very similar to hypoparathyroidism, with low calcium levels and high phosphate levels in the blood. This results in the characteristic symptoms which are generally first seen in childhood. There are two different types of pseudohypoparathyroidism. Type 1A is caused by a mutation in the GNAS gene and is inherited in an autosomal dominant manner. This defect also causes short stature, a round face, and short hand bones, which is referred to as Albright's hereditary osteodystrophy.Pseudohypoparathyroidism type 1A is a genetic disorder that resembles
