GTEx Expression by Gene and Transcript

The heat map summarizes relative expression by tissue type at two levels of tissue detail, e.g., 'Brain' and 'Brain - Amygdala'. Choose among four calculated expression values, including mean and median RPKM values, and quantile normalized (QN) distributions of these values. (Note that differences between some distributions are subtle.) The coloring is relative to the mean of all displayed values. All values are log base 2. (See also PMT GTEx Expression Plotting.) Click on a transcript or tissue to resort the data.
