Our results did prove a statistical association of both rs2228557 and rs12407427 genotypes (TT and CT + CC) and allele (T) with KTCN susceptibility in Iranian population.
The findings disclosed that rs2228557C/T and rs12407427C/T polymorphisms significantly increased the risk of KTCN in measured (codominant1; p = 0.0001, codominant2; p = 0.0001, codominant3; p = 0.0006, dominant; p = 0.0001, over-dominant; p = 0.0005) and (codominant1; p = 0.0001, codominant3; p = 0.0005, recessive; p = 0.0001) inheritance patterns, respectively.
