Ethanol-induced ataxia QTL were mapped using the Interval Mapping module of GeneNetwork. LRS/LOD scores were calculated using 1000 permutations. The algorithm defines two statistical thresholds, suggestive and significant, as defined by Lander and Kruglyak (1995). While no significant linkages were discovered, 10 of the 12 phenotypes defined 13 suggestive ethanol-induced ataxia QTL (Table 2).
