Tissue-specific gene expression heatmap. Transcripts with RPKM values at least three times as high in the indicated tissue than in any other tissues were selected and clustered using R with the package ‘rsgcc’. The color scale indicates the tissue specificity score associated with all transcripts preferentially expressed in the various tissues and organs. The tissue specificity score is 1, if the gene is only expressed in one tissue.
