The risk amino acid (alanine) is on HLA-C*02, *03, *05, *06, *07, *08, *12, *15, *16, *17, and *18 alleles in this sample (including rare alleles), and the amino acid (serine) that is associated with decreased risk of asthma is on HLA-C*01:02, *04:01, *04:07, *14:02, and *14:03 alleles. This evidence concerns the gene HLA-C and asthma.
