∗For Fok-1 polymorphism (rs2228570): F is referred to as T allele, and f is referred to as C allele.
^#For Taq-1 polymorphism (rs731236): T is referred to as T allele, and t is referred to as C allele.
Due to the same base changes T-C or C-T for both polymorphisms, it should be shown as the initial letter of the polymorphism.
