Abstract

• King's syndrome is a sporadic genetic syndrome exhibiting characteristic facial features, short stature, and subclinical myopathy. Affected individuals are susceptible to malignant hyperthermia (MH) induced by anesthesia, stress, or trauma. The incidence of King's syndrome is uncertain as all reported cases were first recognized following an episode of MH. We report a case of King's syndrome without the cryptorchidism and pectus carinatum associated with the syndrome. King's syndrome's possible link to Noonan's syndrome is discussed herein, and the diagnosis and management of MH are briefly reviewed. We recommend evaluation for MH susceptibility in all patients with clinical signs consistent with King's syndrome and in their family members prior to anesthesia.
