Gene distribution of FUS, EWS and Ac-H3K9 ChIP-seq peaks in a gene based model

Protein	All	Exon	Intron	Exon + Intron	Upstream	Downstream	Upstream + Downstream
FUS	134	9	17	1	21	86	0
EWS	241	11	52	2	47	129	0
Ac-H3K9	15115	2510	5911	804	3073	2164	653

Gene distributions were subdivided into six groups: exon, intron, exon + intron (exon is intron sequence in another gene), upstream (10 kb distance), downstream (10 kb distance), and upstream + downstream. The latter specifies a chromosomal localization in where a peak is until 10 kb upstream for one gene but at the same time downstream of a neighboring gene
