[i] The genes are sorted by their loadings on the projection space (PC), which separates the specific tissue. Also provided is the ratio of the mean of the gene expression in the specific tissue sample to the mean of the gene expression in all the other tissues. Genes with large values of the ratio tend to have large PC loadings. In the case of the brain-specific signature, only the top 30 genes as ranked by their loads on PC 2 are provided. A complete list of genes is in Supplementary Materials.
