摘要

We read with interest the article by Rueffert et al. [2004] presenting a patient with a mutation of the ryanodine receptorgene (RYR1) with malignant hyperthermia (MH), central core disease (CCD), and severe skeletal malformation. We evaluated a 6-year-old girl with a history of MH with spondylocostal dysostosis (SCD), including vertebral fusions of L2 and L3 and of L4 and L5 (Fig. 1). Although her muscle specimen showed no specific abnormality indicating CCD, the calcium-induced calcium release (CICR) test for sensitivity for MH indicated calcium-dependent calcium release, supporting her history of MH. In the mutation analysis, we identified a heterozygous RYR1 mutation in exon 47: c.7522C>T; p.R2508C.
