The reference genotype for the ApaI polymorphism is CC. The reference genotype for the TaqI polymorphism is TT.
The reference genotype for the FokI polymorphism is CC. The binary logistic regression test for statistical analysis has been used.
A, adenine; C, cytosine; CI, confidence interval; OR, odds ratio; T, thymine.
