Overview

Malignant hyperthermia in horses

This genetic test detects the RYR1 variant c.7360C>G for malignant hyperthermia, abbreviated MH. Malignant hyperthermia is an inherited susceptibility in which muscle cells release too much calcium after specific triggers.

In susceptible horses, an episode can be triggered by anesthesia, stress, exercise or other challenging conditions. Episodes can progress rapidly with muscle rigidity, high body temperature, fast heart rate, breathing problems, acidosis and muscle breakdown.

Practical value of this test

  • N/N: the tested MH variant is not detected.
  • N/MH: one copy causes MH susceptibility and can be passed on.
  • MH/MH: two copies cause MH susceptibility and are passed to all offspring.

The result is valuable for breeding selection and for identifying horses whose anesthesia and stress management should be planned with extra care.
