From: Who’s afraid of the X? Incorporating the X and Y chromosomes into the analysis of DNA methylation array data
Study design
Method
Case vs. control
Sex-stratified (e.g., X chromosome DNAme in XX female case versus unaffected XX female controls)
X-chromosome inactivation
Use average CpG island promoter DNAme to evaluate whether X linked genes escape or are subject to XCI, as demonstrated in [22, 43]
