Denodogram of the 41 cases from a single run of the MCMC algorithm under the general alternative model of association with the PDM phenotype for 32 marker SNPs across an 890-kb region flanking the CYP2D6 gene. The dendogram is constructed to illustrate the relatedness of individuals in terms of the posterior mean number of haplotypes they share from the same cluster (fig. 3). Individuals with PDM are coded according to their genotype at functional polymorphisms in the CYP2D6 gene, where 1 is the G1846A mutation, 2 is the delA2548 mutation, and 3 is the delT1707 mutation.
