In susceptible individuals, halogenated anaesthetics and\/or suxamethonium may trigger an MH reaction. The diagnosis of MH susceptibility is made by an <jats:italic>in vitro<\/jats:italic> contracture test of biopsied muscle strips.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> In 27 MH susceptible (MHS) probands and four MH negative (MHN) probands, exons 17, 39, 40, 45 and 46 of the <jats:italic>RYR1<\/jats:italic> gene were screened for MH causative mutations. In addition, in three patients with established central core disease (CCD), exons 17, 39, 40, 45 and 46 and exons 95, 100, 101 and 102 were screened for MH and CCD causative mutations. All screenings were performed by direct sequencing of the entire exons.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> MH causative mutations were found in five of the 27 MHS probands (19%). CCD causative mutations were found in two of three CCD patients in the C\u2010terminal exons. None of the CCD patients showed a mutation in N\u2010terminal exon 17 or in the central exons.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> In a Swedish population, screening of N\u2010terminal exon 17 and the central exons for MH causative mutations in the <jats:italic>RYR1<\/jats:italic> gene covers 19% of families. Thus, other mutations must also be responsible for MH susceptibility in Sweden. Although the number of CCD patients in this study was small, screening of the C\u2010terminal exons for CCD causative mutations seems to be a promising tool in the process of making a diagnosis.<\/jats:p>","DOI":"10.1111\/j.1399-6576.2006.01165.x","type":"journal-article","created":{"date-parts":[[2006,11,1]],"date-time":"2006-11-01T16:36:39Z","timestamp":1162398999000},"page":"50-53","source":"Crossref","is-referenced-by-count":9,"title":["Malignant hyperthermia and central core disease causative mutations in Swedish patients"],"prefix":"10.1111","volume":"51","author":[{"given":"M.","family":"Broman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Islander","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
