ical factor in LOD-score analysis is the MOI at the linked locus, not that of the disease or trait per se. Thus, a limited set of simple genetic models in LOD-score anal- ysis can work well in testing for linkage. Received October 23, 1997; accepted for publication June 22, 1998; ...

Lod ScoreLod score stands for (decadic) logarithm of the odds ratio. In genetic linkage analysis, the lod score quantifies the empirical evidence in favour of linkage between two loci of interest. Genetic...doi:10.1007/3-540-29623-9_7676E. Thompson...

assuming several different sets of genetic parameters is usually necessary. Having to test multiple genetic parameters increases the type 1 error, but recent work has shown that this increase is minimal (Knapp et al. 1994). Lod score analysis has important advantages for the study of autoimmuneend...
We present a recoding scheme that allows for a parametric multipoint X-chromosomal linkage analysis of dichotomous traits in the context of a computer program for autosomes that can use trait models with imprinting. Furthermore, with this scheme, it is possible to perform a joint multipoint ...
When there is some knowledge about the prevalence of the disease under study and the level of familial aggregation, a common procedure to reduce the risk of misspecification is to generate a limited number of realistic genetic models to use in lod score analysis. However, when performing the ...
