[i] ^aIncludes the base pairs between CpGs that had sufficient read coverage for the LD analysis.

[ii] ^bLD blocks are defined as regions that span >100 bp and contain >10 CpG dinucleotide pairs whose r² > 0.3. Female cell lines, containing two X chromosomes, are expected to show LD blocks in regions of X chromosome inactivation.

[iii] ^cPercentage of LD blocks not located in chromosome X or known imprinting genes.
