Evolutionary tree and network of DTNBP1 8-SNP haplotypes. (a) The evolutionary tree reconstructed by the neighbor-joining method in MEGA 4.0. (b) The haplotype network generated by the median-joining algorithm in software NETWORK 4.2.01. Seven gray circles denote the seven haplotypes in van den Oord et al.7 Among them, haplotype 2 is the high-risk haplotype and haplotype 1 is the common haplotype. Circle areas are proportional to haplotype frequencies. Four octagon nodes denote the four non-human primates.
