TCF21 and coronary artery disorder: We suppose that lncRNA RP3-323P13.2 (also known as TARID; locus #20) indicated by our SMR/HEIDI analysis can in the same way be relevant for CAD via the regulation of expression of CAD-associated gene TCF21. In the study by Arab et al. 58, TARID was shown to activate TCF21 expression via interaction with TCF21 promoter as well as with the regulator of DNA demethylation GADD45A.
