Figure 1. Twelve immune diseases and disorders included in all genome-wide association (GWA) studies conducted between 2008 and 2010. The Y-axis indicates the names of the genes, and X-axis indicates the genomic locations. The dark vertical bars indicate the location of the HLA-genes in relations to the association signals. The diseases are expressed using different shapes. Different studies are labeled with colors. For instance, celiac disease is expressed using a red triangle, lupus is expressed using a purple dot, and leprosy is expressed using a blue triangle.
