In the current study, for the first time, we aimed to evaluate the association between SNPs located within miR-137 (rs1625579A/C) and its target genes TCF4 (rs1261084C/T) and CACNA1C (rs10774053A/G and rs10466907G/T) and the risk of BD in an Iranian population. Here, TCF4 is linked to Behcet disease.
