A novel type 1b pseudohypoparathyroidism gene mutation in an adult with dilated cardiomyopathy and massive pericardial effusion

Pseudohypoparathyroidism (PHP) is a medical condition that affects calcium-mediated myocardial membrane depolarization [1] and cardiac contractility. Hypocalcemic ventricular dysfunction secondary to parathyroid dysfunction is a rare event in adults [2] that responds promptly to restoration of normocalcemia.
