MICA: major histocompatibility complex (MHC) class I chain-related gene A; AITD: autoimmune thyroid diseases; HD: Hashimoto’s disease; GD: Graves’ disease; C: healthy control subjects; allele frequencies of MICA were in the Hardy-Weinberg equilibrium (P < 0.349); aP < 0.003 ( < 0.042), OR = 2.21 (95% confidence interval (CI), 1.30–3.76) versus C.
