Nucleotide sequence of haplotypes I and II of the hAT1R gene. Human AT1R gene contains four polymorphic sites in its promoter that are in LD. Haplotype I contains nucleosides T, T, A, and A at −777, −680, −214, and −119, respectively, in its promoter. Haplotype II contains nucleosides A, G, C, and G at these positions.
