Extended Data Fig. 6: Somatic mutation rate and burden frequency by type of region tested.

a, Number of mutated regions tested per gene with somatic burden frequency ≥ 1%. b, Mutation rate per kilobase. c, Burden frequency, stratified by the type of interval tested (flanking, exonic or intronic). d, Distribution of distances (bp) of the leading intervals (FDR ≤ 5%) to the closest (left and right) interval such that the association P value decreases by at least one order of magnitude (99% of the distribution is shown). e, Breakdown of all genomic regions tested (n = 1,049,102 with burden frequency ≥ 1%) and of the 567 genomic regions that underlie the observed somatic cis-eQTL at a FDR of 5% (intronic denotes eGene intron; exonic denotes eGene exon; flank. denotes 2-kb flanking region within 1 Mb distance to the eGene start and end; flank.intergenic denotes flanking region in a genomic location without gene annotations; flank.intronic denotes flanking region overlapping an intron of a nearby gene; and flank.others denotes flanking region partially overlapping several annotations of a nearby gene).
