  • Title: Haplotype sharing tests of linkage disequilibrium in a Hutterite asthma data set.
    Author: Levinson DF, Nolte I, te Meerman GJ.
    Journal: Genet Epidemiol; 2001; 21 Suppl 1():S308-11. PubMed ID: 11793689.
    Abstract:
    The Genetic Analysis Workshop 12 genome scan data set for "strict" asthma in a Hutterite population was analyzed using haplotype sharing analysis (HSA), which tests for differences in mean length of haplotype sharing around each marker for pairs of chromosomes in cases versus controls. The regions of chromosome 1 and 8 where evidence for linkage was observed in published analyses were negative by HSA. HSA yielded positive results on chromosomes 7, 12, 16, 18, and 21 (p = 0.003 on 21q). Although there are reports of support for linkage to asthma in some of these regions, it is not known whether any represent true positives. Further study is needed of the possible role of length-based measures of linkage disequilibrium in recent population isolates.
