The rs2430561 polymorphism of IFN[gamma] (+874T/A)is in complete linkage disequilibrium with the number of CA repeats in the first intron, which is associated with the amount of IFN[gamma] production.
They also observed a high degree of redundancy in CA repeats and suggested GA repeats as an alternative source of polymorphism.
