Malignant hyperthermia (MH) has been reported as non-existent in children
less than 1 yr old, although several unconfirmed reports have been
published. A case report of MH in a 6-month-old child is presented, with
confirmation of MH susceptibility by in vitro contracture testing of
quadriceps muscle at 13 yr old. Genetic analysis revealed a novel RYR1
mutation that substitutes arginine 2452 for tryptophan in a region of the
calcium channel mutated in several other MH pedigrees.
