Overview
Patients with pseudohypoparathyroidism type1a, type 1c and pseudopseudohypoparathyroidism present by the second decade of life with characteristic physical features of Albright's hereditary osteodystrophy. Pseudohypoparathyroidism type 1B isolated resistance to parathyroid hormone without the associated clinical features of Albright's osteodystrophy. Mild brachydactyly is seen in some cases. Blomstrand's chondrodystrophy presents with short limbs due to characteristic growth impairment. Secondary hyperplasia of the parathyroid glands occurs as a result of associated hypocalcemia.
