Antisense non-coding RNA in the INK4 locus (ANRIL) is a long non-coding RNA (lncRNA) located in the antisense direction of the INK4B-ARF-INK4A motif cluster of 9p21 chromosomes, and its gene single nucleotide polymorphism is associated with a variety of atherosclerotic vascular diseases such as coronary heart disease and myocardial infarction [9]. Here, CDKN2B-AS1 is linked to myocardial infarction.
