Heat map showing hierarchical clustering of tissues based on global gene expression.

<p>Clustering was based on log₂-transformed Fragments Per Kilobase Exon model per Million mapped fragments (FPKM) values of 29,038 genes that were detected in at least one tissue based on the FPKM 95% confidence interval lower boundary greater than zero. Red, yellow, and blue colors indicate high, medium, and low levels of gene log₂-transformed expression, respectively.
