In this respect, Michel et al. [59] indicated that only 37% of the previously associated SNPs from 14 candidate genes were captured by the array utilized by the same authors on the first GWAS for asthma and, surprisingly, not a single SNP from key asthma genes such as ADAM33, IL4 and CD14 was contained in their array [8]. The gene discussed is ADAM33; the disease is asthma.
