During the 1990s there was an increase in suicide rate which largely remains unexplained. From 1997, there has been a general reduction in suicide rate, again, largely unexplained. Of interest is a fall in suicide rates from 1935 to 1945. This is the usual response during wartime, and is believed to be because the community draws together against a common enemy. Also of interest is the increase in suicide rate from the early 1960s, lasting till the late 1960s. However, the Vietnam War divided the people of Australia, with public protests and great public unease, which may explain this apparent anachronism.

One approach is to try to reduce loci of interest, with the expectation that they will share genetic heterogeneity in the patient sample by studying ge- this information with the scientific community. For in- netically isolated populations or by narrowing the affected stance, SNP variants in the coding or regulatory regions phenotype under study based on criteria of severity or the of genes (cSNPs) may cause functional differences in gene presence of a biological marker for the disease. With such variants catalogued in advance, it will approach is to greatly expand the sample size and number be relatively straightforward to test multiple candidate genes of DNA markers used in genetic association studies to in- for association with a disease phenotype or a pharmacoge- crease the power to detect multiple possible genes contribut- netic effect.

The HGP, begun in 1990, is a joint effort coordinated by the U. Department of Energy and Principles of Genetic Mapping:The the National Institutes of Health, with the cooperation in Search for Identity by Descent recent years of international entities such as the Wellcome Trust in Great Britain (3). The next subsection describes how innovations in ge- disease gene under study. The principle behind this expecta- netic maps and the structure of genetic mapping studies tion is best illustrated by considering genetically isolated or may eventually lead us to identify the as yet elusive genes founder populations (7,8). A founder population descends for psychiatric disorders. The shared segment includes the markers that sand markers spaced at roughly 1 to 5 centimorgans (cM); flank the disease gene. These markers are said to be linked 1 cM is a unit of genetic distance equivalent to a recombina- to the gene since, because of their close physical proximity, tion frequency between two loci of 1%, i. Detection of linkage is the goal are under construction now, however, as part of the HGP.

If LD is observed tide polymorphisms (SNPs) are thought to constitute between the same markers over a region greater than occurs roughly 90% of sequence variation in humans. Occurring at random in a sample of patients, it may indicate that they at an average spacing of 1 SNP per 1,000 base pairs (1 share this segment of DNA IBD and that it harbors a disease kilobase, kb), they will thus constitute the majority of the gene. Detection of LD is a goal of population-based genetic markers in the planned high-density map. For example, a sample of affected individuals separated facilitate detection of population genetic variation in their by roughly 15 generations from their common ancestors 18: Using Human Genomics to Advance Neuropsychopharmacology 233 Pedigree-Based Mapping Studies: Problems and Solutions Linkage analysis of pedigree data has been a very successful method of mapping genes for rare single gene disorders with distinct phenotypes such as cystic fibrosis (11). There are many limitations on the use of linkage analysis for complex traits, however. Linkage analysis is a statistical means of quantifying the likelihood that the observed segregation of marker alleles within a family supports the hypothesis of linkage versus nonlinkage to a disease gene. Traditional link- age analysis is model-based or parametric, meaning that it requires specification of disease inheritance parameters that are not easily estimated for psychiatric disorders, such as the frequency of the disease allele, the genotype specific penetrance, or even the number of genes likely involved. The lack of knowledge of these parameters means that data FIGURE 18. Genetic mapping studies in isolated populations must be analyzed under a number of different models.
