Among the named genes that were significantly different between the CA and W groups (Table 1), there were 43 genes located within rat QTLs for alcohol consumption and preference (Bice et al., 1998; Carr et al., 1998, 2003; Foroud et al., 2003). There were 11 genes located within Alc18 on chromosome 4, 6 genes located within Alc15 on chromosome 2, and 5 genes located within Alc8 on chromosome 3. Four or fewer genes were located within each of the following: Alc6 on chromosome 12, Alc11 on chromosome 16, Alc17 on chromosome 6, Alc5 on chromosome 10, Alc10 on chromosome 12, and Alc20 on chromosome 8 (Table 1).
