  1. The 8 expression categories are described in the Figure 7. HE, High Expression; LE, Low Expression; SR Small Range of expression; WR, Wide Range of expression; HE+ Highest Expressions; LE+, Lowest Expressions. The whole gene set contains the 11161 genes for which we have both a known TSS and CATMA-expression data. We performed two one-sided Fisher exact tests allowing the identification of higher (bold) or lower (underlined) percentages in a gene set in comparison with all other genes, i.e. genes within the whole gene set minus genes within the considered gene set. NS indicates non-significant difference. P-values in parenthesis are less than 5% with the Bonferroni correction.
