Our results showed that the AG genotype and the minor allele G frequency of rs1131665 and rs1061502 in AITD patients were both higher than those of the controls (rs1131665: AG genotype: <i>P</i> = 0.017, OR = 1.968; allele G: <i>P</i> = 0.018, OR = 1.946; rs1061502: AG genotype: <i>P</i> = 0.029, OR = 1.866; allele G: <i>P</i> = 0.031, OR = 1.847).
