Malignant hyperthermia (MH) is a potentially fatal autosomal dominant disorder of the skeletal muscle and is triggered in susceptible individuals by commonly used inhalation anaesthetics and depolarizing muscle relaxants. Around 80% of the affected family are linked to the ryanodine receptor (RYR1) gene. More than 300 mutations in RYR1 have been associated with the MH-susceptible phenotype. Here we report the identification by two independent methods of a novel mutation associated with the MH-susceptible phenotype in the RYR1 gene.
