A 22-year-old woman presented to us with seizures of a few minutes duration. She had clinical features of Albright hereditary osteodystrophy (AHO), including hypocalcemia, hyperphosphatemia and resistance to parathyroid hormone. Genetic testing revealed a sporadic form of pseudohypoparathyroidism type Ib (PHP-Ib). This is the first Japanese case involving overlap between pseudohypoparathyroidism type Ia (PHP Ia) associated with AHO and PHP Ib. It is important to perform both DNA sequencing and methylation status analyses in cases of suspected PHP in patients with signs of AHO.
