Chromosomal regions with multipoint LODs greater than 1.5 for DSM-IV NW in sample specific or combined sample analyses are listed in Table 2. For the Australian sample a multipoint LOD of 1.68 was found on chromosome 11 at 123 cM. For the Finnish sample, a multipoint LOD of 1.93 was found on chromosome 6 at 75cM and a LOD of 3.55 on chromosome 11 at 17 cM. Combining the samples a LOD of 2.30, that was larger than LOD scores found in either sub-sample, was observed on chromosome 11 at 123 cM (see Figure 1 and Figure 2). The multipoint LOD of 3.55 at 11p15.5 in the Finnish sample met genomewide significance (p = 0.013). The highest single point marker in this region yielded a LOD = 2.34 (at D11S1338). The chromosome 11 findings are plotted in Figure 2.
