Association study of miR-149, miR-196a2, and miR-499a polymorphisms with coronary artery aneurysm of Kawasaki disease in southern Chinese population.

Our results demonstrated that the miR-149 rs2292832 T>C polymorphism increased the risk of CAA in KD patients and that the miR-499a rs3746444 A>G polymorphism decreased the risk of CAA in KD patients. Further studies with larger sample sizes and different centers are needed to confirm the findings of the present study.
