Short metacarpals and/or -tarsals are observed in pseudohypoparathyroidism (PHP) type Ia (PHP1A) or pseudo-PHP (PPHP) caused by inactivating GNAS mutations involving exons encoding the stimulatory G protein alpha-subunit (Gαs). Skeletal abnormalities indistinguishable from those caused by Gαs mutations were present in five members of an extended Belgian family, who showed no evidence for abnormal regulation of calcium and phosphate homeostasis.
