Dimensionality reduction by principal components analysis based on log2 normalized counts of all genes for all participants. Each dot corresponds to the sample of one participant. The smaller the distance between the dots, the greater the similarity of the gene expression profiles. PC1, principal component 1; PC2, principal component 2; percentage expresses contribution to the overall variability in the data
