Genome-wide screens for asthma and atopy susceptibility loci have been completed in six population samples. Despite the extensive clinical heterogeneity associated with these phenotypes, 20 chromosomal regions show evidence of linkage (P < 0.01) in three or more population samples. Thus, this survey suggests that at least 20 independent loci influence susceptibility to asthma, atopy, or associated phenotypes and indicates that the genetics of these phenotypes are truly complex. Ongoing studies are aimed at identifying the specific gene or genes in these regions that confer susceptibility to asthma or atopy.
