We have identified two regions that showed some evidence of linkage with alcoholism on chromosome 2 and chromosome 7 from both the microsatellite and the SNP scans. For these regions, we had stronger linkage signals using the SNPs than those using the microsatellites. Although results from the two scans had good overall concordance, three regions of significant linkages were detected in the SNP scan but not in the microsatellite scan. Lastly, the difference in IC between the SNPs and the microsatellites might explain the different results observed in the two scans.
