NOTE.—(A) Three sites with SNP (174, 581, and 629) were observed in the 5′ LTR of K113. None of the Caucasians had any SNP in any of these three sites indicating all of them had the same allele of K113. Both African Americans and Hispanics had at least two SNPs in each locus. There was an additional base at position 581 in African Americans. Base frequencies at each base were biased toward one common base. (B) Four SNP sites (286, 385, 410, and 687) were identified in the 5′ LTR of K115. All the Caucasians had the same allele of K115. African Americans had two bases at each of the SNP sites with a similar base frequency except at position 410 in which base frequency was biased. Hispanics did show diversity at all three sites but did not have an SNP at position 410. All SNPs were numbered according to their position in GenBank sequences AY037928 for K113 and AY037929 for K115.
