Albright's hereditary osteodystrophy

The authors observed different clinical forms of Albright's hereditary osteodystrophy in 4 members of a family (two sisters, their mother and the maternal grandfather). The sisters were affected by pseudohypoparathyroidism type I, the older manifested the hypocalcemic variety, the younger the normocalcemic variety; the mother and the grandfather presented only with short stature and subcutaneous calcifications. The variety of clinical and biochemical alterations observed in these 3 generations supports evidence that Albright's hereditary osteodystrophy has a broad spectrum and that distinctions between the various forms of pseudohypoparathyroidsim should not be rigidly considered.
