For the rs12976445polymorphism, genetic associations between the combinational genotype and HT risk were also found in the dominant model and overdominant model.
We determined that the CC genotype and C allele of the rs12976445 C/T polymorphism were significantly more frequent in patients with HD compared with control subjects (P < 0·05) and in intractable GD compared with GD in remission (P < 0·05).
