There are three loci of interest for the ASPD/CD phenotype found in this American Indian study that were in a similar location to those identified in previously published linkage analyses for externalizing behaviors. A broad region on chromosome 3 supporting evidence suggestive of linkage for ASPD/CD in these American Indians was found in a similar location (within 30 cM) by another study for conduct symptoms (Stallings et al., 2005) and drug abuse vulnerability (Stallings et al., 2003).
