Functional annotation of lincRNAs based on adjacent protein-coding genes. a: Overview of distances from lincRNAs to their proximal protein-coding genes within 20 kb. Red dashed line at about 12 kb shows the median distance for all flanking protein-coding genes. b: Density of expression correlations between different gene groups by all samples. c: Density of expression correlations between different gene groups by 162 high quality samples. d: Significant categories enriched among protein-coding genes adjacent to lincRNAs within 20 kb
