Pseudohypoparathyroidism: report on a family with four affected sisters.
A family consisting of a mother, a father with probable pseudopseudohypoparathyroidism (PPHP), two normal daughters, and four daughters with pseudohypoparathyroidism (PHP) have been observed for more than 15 years at North Carolina Memorial Hospital (NCMH). The studies performed on family members included (1) roentgenographic examinations of the chest, skull, hands, and soft tissues; (2) serum calcium, phosphorus, and immunoreactive parathyroid hormone measurements; (3) urinary cyclic adenosine 3'5'-monophosphate determinations following parathyroid injection; and (4) HLA and blood-type determinations. We review the genetic aspects of PHP. The findings in this family suggest an autosomal dominant mode of transmission in PHP.
