Fig. 6From: Genome annotation for clinical genomic diagnostics: strengths and weaknessesDifferent classifications of long non-coding RNAs (lncRNAs). The classification of lncRNAs is based on their position with respect to coding genes. lncRNAs are illustrated here with only red exons, whereas the coding genes are shown as red and green. AS antisense, BDP bi-directional promoter, lincRNA long-intergenic RNA (not overlapping a protein-coding locus on either strand), OS overlapping sense, O3′ overlapping 3′, SI sense intronic.
