The impact of methylation quantitative trait loci (mQTLs) on active smoking-related DNA methylation changes
Background: Methylation quantitative trait loci (mQTLs) are the genetic variants that may affect the DNA methylation patterns of CpG sites. However, their roles in influencing the disturbances of smoking-related epigenetic changes have not been well established. This study was conducted to address whether mQTLs exist in the vicinity of smoking-related CpG sites (±50kb) and to examine their associa
