Description
This panel contains genes that encode skeletal muscle channel proteins, and associated with malignant hyperthermia and periodic paralysis (hyperkalemic, hypokalemic/thyrotoxic, normokalemic potassium-sensitive)/congenital myotonia. It is maintained by the Royal Melbourne Hospital and is a consensus panel used by VCGS.

This panel has been compared against the Genomics England PanelApp "Skeletal Muscle Channelopathy" panel with all discrepancies resolved, and reciprocal feedback provided to Genomics England, 20/8/20.
