Multipoint LOD scores for alcohol dependence symptom score are shown for Younger and Older samples (identical except for a subset of 822 individuals for whom data were collected on two occasions with first occasion data included in the Younger dataset and second occasion data in the Older dataset) and for full (100%) and truncated (~90%) samples. Gene locations are shown for the GABAA and ADH gene clusters and CHRM2, all of which have been associated with alcohol phenotypes in multiple studies (Edenberg and Foroud, 2006) and GAD1, SLC1A3, and CDH12, which are candidate addiction genes found under current linkage peaks.
