| Description |
Sample name: X71
normal whole blood sample
|
| Data processing |
BeadStudio softwarewas used to process the raw signal. After the beta values are calculated (Beta value=methylated signal/(methylated signal+unmethylated signal), data quality control was implemented using R (http://www.r-project.org/) (version 2.15.3). We removed 17,764 CpG sites for which probes mapped to multiple loci in the human genome reference sequence. CpG sites that are SNPs, that had missing values, or that had detection p-values >0.01 were excluded. Methylation data from probes mapping to the X and Y chromosomes were excluded. We were left with 394,354 CpG sites from 100 individuals in downstream analyses.
