Article
Recent linkage findings for psychiatric disorders, in particular schizophrenia, manic-depression, and Alzheimer disease, have raised a number of important conceptual issues regarding the genetic etiology of these diseases, as well as the appropriate interpretation of linkage results in studying complex diseases. Perspectives on mode of inheritance,...
Article
A two-parameter (admixture) test (Lod2) for the detection of linkage which allows for heterogeneity is described. Lod score values for this test which lead to comparable type 1 error probabilities as the conventional (homogeneous) single-parameter lod score test (Lod1) are derived. For example, a Lod2 value of 3.70 corresponds to the conventional l...

... This disease locus is presumed to lie at some map position x relative to the marker loci. The hypothesis of linkage with admixture due to locus heterogeneity assumes that a certain proportion, α, of families have disease due to the actions of a locus at this position whereas (1 − α) families manifest the effects of a locus with the same disease model parameters but at an unlinked position (Risch, 1989). The null hypothesis of no linkage assumes α = 0. ...
... Both family and adoption studies have suggested that several genetic loci are involved in the genesis of SCZ [59]. Linkage analyses of schizophrenic genes that have been performed on chromosomes 2q [60], 3p [61], 4p [62], 5q [63] , and 22q [64,65] around the world whereas the first study from Pakistan performed haplotype and linkage disequilibrium analysis association of DISC locus (1q24.1) ...
