PSEUDOHYPOPARATHYROIDISM TYPE 1B

Alternate names

PSEUDOHYPOPARATHYROIDISM TYPE 1B Is also known as php ib

Description

Pseudohypoparathyroidism type 1B (PHP-1b) is a type of pseudohypoparathyroidism (PHP; see this term) characterized by localized resistance to parathyroid hormone (PTH) mainly in the renal tissues which manifests with hypocalcemia, hyperphosphatemia and elevated PTH levels. About 60-70% of patients also present with elevated TSH levels due to TSH resistance.

Most common symptoms of PSEUDOHYPOPARATHYROIDISM TYPE 1B

  • Intellectual disability
  • Seizures
  • Short stature
  • Nystagmus
  • Cataract
