Genes were found within a 2-Mb window centered on each SNP, and overrepresentation of particular functions was detected using the PANTHER gene classification system. The observed number of genes in the genome, the observed number of genes in candidate regions, and the expected number of genes in candidate regions are denoted by Genome, Regions, and Expected, respectively, for each functional class.
