NOTE.—n/a, not applicable; n, number of alleles sampled; h, number of haplotypes; S, segregating sites; bp, sequence length in base pairs; π is nucleotide diversity per base pair; ns, nonsynonymous; s, synonymous. The US population was both analyzed as a whole and split into haplotype groups. Tajima's D (Tajima 1989) includes all mutations. Z_nS (Kelly 1997) is linkage disequilibrium based on segregating sites. Statistically significant values (*0.01 ≤ P < 0.05; **0.001 ≤ P < 0.01; ***P < 0.001) under a null demographic model are indicated (*) for the 5′ gene region and intron 2 in the New York population and the “A” haplotype group (see table 2).
