Focusing on ATH, we discuss the relationships between the Alu elements and two other families of ncRNAs, with a known involvement in ATH progression, namely, a group of small microRNAs (miRNAs), and the lncRNA ANRIL, with specific alleles that have been acknowledged as risk factors for CAD (see Section 4). This evidence concerns the gene CDKN2B-AS1 and coronary artery disorder.
