From: Maternal blood contamination of collected cord blood can be identified using DNA methylation at three CpGs

Fig. 1

Principal component and X chromosome DNA methylation (DNAm) patterns revealed maternal blood contamination in cord blood. a Plotting the first two principal components of 450K DNAm data identified a number of male samples with DNAm patterns similar to female participants or intermediate between male and female. b Examining the distribution of X chromosome DNAm beta values in these samples revealed that the intermediate male samples clearly showed patterns indicative of a mixture of male (top) and female (bottom) distributions
