Genomic location of ANRIL (CDKN2B-AS1) and its splicing variants. ANRIL resides in 9p21 locus and spans approximately 126 kb of genomic DNA, comprising 20 exons in total (black rectangles) and 14 splicing isoforms annotated in RefSeq records. The main regulatory elements are depicted below the scale bar. The discussed SNPs are indicated above the ANRIL exons. The orientations of primers are displayed by arrows above the exons. ANRIL, antisense noncoding RNA in the INK4A locus. CTCF CCCTC-binding factor.
