title: Hypersensitivity to suxamethonium in a Suffolk family.
abstract: Suxamethonium apnoea developed in a patient who was a homozygote for the atypical gene. Fifty-five members of the patient's family were investigated. Seven further homozygotes were found. Suxamethonium apnoea had been demonstrated previously in one of these. Thirty-two members of the family were heterozygotes.
