Description Dried blood spots for Pb and DNA methylation study
Data processing Sample normalization done using Bioconductor package ChAMP. Type1 to type 2 probe bias correction was done using Beta mixed interquantile range normalization. Based on gender differences in DNA methylation profile the representative DNA methylation loci was divided into conserved female specific and male specific regions. The CpG sites show highly correlated changes in methylation signatures and can be defined as co-regulated regions. The co-regulated regions were assigned to specified clusters using the A-clustering algorithm (Sofer et al 2013). The association between Pb concentration measured in dried blood spot and DNA methylation of coregulated region for conserved female specific and male specific regions was calculated using Generalized estimating equations (GEE) (Sofer et al 2013)
