CDKN2B-AS1 and myocardial infarction: They believed that the differential expression of MIAT in the presence of different alleles of rs2331291 polymorphism plays a role in MI pathogenesis.19 In further analysis, an increased risk of MI was seen in the presence of a susceptible allele of the rs1333049 polymorphism in ANRIL lncRNA gene.20 Gao et al demonstrated the relationship between H19 lncRNA and the susceptibility to CAD in a Chinese population.21 In a year after, Huang et al examined the association between the common variant in CDKN2BAS lncRNA and coronary heart disease.
