1Symbols with asterisks indicate alleles, and symbols without asterisks indicate serologically defined antigens. For each disease, the marker or markers with the strongest associations are given. In many cases in which it is difficult to decide whether HLA-DR or -DQ markers are responsible for association, both markers are given.
2The relative risk indicates the frequency of a disease in persons with the HLA marker as compared with persons without the marker. A positive association (ie, when the HLA marker is more frequent in persons with the disease than in those without it) is indicated by a relative risk of more than 1.0, a negative association by a relative risk of less than 1.0, and no association by a relative risk of 1.0.
3The risk has not been assessed separately for this allele.
