Subtelomeric regions bear transcriptionally active clusters of ncRNAs. (a) Genomic overview of subtelomeric regions of the left arm of chromosome 1 showing a cluster of transcribed segments with no protein-coding potential. Different classes of TelRs are represented. (b) Schematic representation of genomic organization of the different classes of TelRs at chromosome arms. TLO genes along with subtelomeric ORFs are shown.
