Classification
Pseudohypoparathyroidism is classified based on the measurement of serum and urinary cAMP and phosphate excretion levels after injection of biologically active parathyroid hormone. The following are the different types of pseudohypoparathyroidism:[1]
- Pseudohypoparathyroidism type I
- Pseudohypoparathyroidism type II
Pseudohypoparathyroidism type 1 is further classified into following subtype:
- Pseudohypoparathyroidism type 1a
- Pseudohypoparathyroidism type 1b
- Pseudohypoparathyroidism type 1c
- Pseudopseudohypoparathyroidism
Other forms of parathyroid hormone resistance include :
- Blomstrand syndrome
- Acrodysostosis type 1
- Acrodysostosis type 2
