-
A type of pseudohypoparathyroidism with characteristics of resistance to parathyroid hormone (PTH), which manifests with hypocalcaemia, hyperphosphataemia and elevated PTH levels, absence of Albright\'s hereditary osteodystrophy and normal expression of the Gs protein with a normal urinary cAMP response. To date no specific genetic alteration responsible for this disorder has been detected. It has been hypothesised that in most cases it may be an acquired defect secondary to vitamin D deficiency such as in misdiagnosed secondary renal hyperparathyroidism.
