Genetic markers of statin-induced myopathy

Genetic studies identified SNPs that could help stratify patients based on their risk for statin-induced myopathy. Use of statin drugs such as simvastatin is associated with a small increase in risk of myopathy. In an analysis of gene expression in lymphoblastoid cell lines derived from 480 subjects in a clinical trial of simvastatin, six SNPs at the glycine amidinotransferase (GATM; AGAT) gene locus were associated with decreased risk of statin-induced myopathy. Next steps include assessing the role of GATM in statin-mediated changes to cholesterol metabolism and muscle health.
