Description
This panel contains genes that are established causes of malignant hyperthermia susceptibility (MHS). It can be used when the clinical and laboratory findings suggest a diagnosis of MHS, such as a positive muscle biopsy contracture test or positive family history. This panel is used by the Royal Melbourne Hospital.

The Skeletal Muscle Channelopathies, Rhabdomyolysis, or Myopathy panels may considered where the clinical presentation is less clearly indicative of malignant hyperthermia.
