The full results of the exploratory linkage analysis of withdrawal, severe drinking, and medical/mental health symptoms are presented in Table 4. The strongest result was observed for symptoms of severe drinking on chromosome 1 at 20 cM (LOD = 3.08). LOD scores greater than 2.0 were also observed for severe drinking symptoms on chromosome 2 at 41 cM (LOD = 2.12) and chromosome 19 at 33 cM (LOD = 2.62) and for withdrawal symptoms on chromosome 9 at 161 cM (LOD = 2.06).
