In KD with coronary artery lesions (KD-CAL) group, the genotype frequencies of GG were higher than that in KD without coronary artery lesion (KD-WO) group at locus rs2910164 G/C polymorphisms of miR-146a gene (χ<sup>2</sup> = 6.660, P = 0.036), patients with KD carried genotype of GG were at 3.636 times higher risk of getting coronary artery lesions than those of non-carriers (χ<sup>2</sup> = 6.455, P = 0.018, OR = 3.636, 95%CI = 1.280-10.262).
The present study indicates that the <i>miR-146a</i> rs2910164 C>G polymorphism may not be associated with Kawasaki disease in the southern Chinese population.
