Pseudohypoparathyroidism is a condition caused by resistance to the parathyroid hormone. Patients have a low serum calcium and high phosphate, but the parathyroid hormone level is appropriately high.
- Type 1a pseudohypoparathyroidism has a characteristic phenotypic appearance (Albright's hereditary osteodystrophy), including short fourth and fifth metacarpals and a rounded facies.
- Type 1b pseudohypoparathyroidism lacks the physical appearance of type 1a, but is biochemically similar.
The term pseudopseudohypoparathyroidism is used to describe a condition where the individual has the phenotypic appearance of pseudohypoparathyroidism type 1a, but is biochemically normal.
