SLC24A1 and asthma: From the genotyping of the 26 variants in the full Hutterite sample, we identified five variants with nominally significant associations to asthma in the Hutterites and had allele frequencies less than 0.05 in other populations of European ancestry, including the deletion in SLC24A1, and the allele frequencies of these variants range from 1%–6% in the Hutterites (Table 2).
