Abstract:
:Previously, we demonstrated evidence of linkage to bipolar affective disorder (BP) in a single large, multigenerational family with a LOD score of 3.41 at the PFKL locus on chromosome 21q22.3. Additional families showed little support for linkage to PFKL under homogeneity or heterogeneity, in that study. We have expanded on that analysis, with 31 microsatellite markers at an average marker spacing of =2 cM, in the largest multigenerational BP pedigree series reported to date. A two-point heterogeneity (alpha=0.5) LOD score of 3.35 (P<.000156) was found at the D21S1260 locus, 5 cM proximal to PFKL. Polylocus analysis with a cluster of three neighboring markers was consistent with these results (PL-HetLOD = 3.25). In the design of this study, 373 individuals from 40 families (from a total set of 1,508 individuals in 57 families) were chosen, as a cost-effective approach to genotyping this large sample set. Linkage analyses were performed with an "affecteds-only" method. As such, our results are based solely on genetic information from affected individuals, without assumptions about the disease-locus genotypes of the unaffecteds. Furthermore, for ease of comparison, this study was performed with the same approach as a 10-cM genome scan for BP loci, the results of which will be reported elsewhere.
