Abstract
An association and linkage study of the HLA [human leukocyte antigen] system and bipolar affective illness is reported. HLA B-14 showed an increased frequency and HLA-Bw27 a decreased frequency in 92 bipolar patients compared to 210 controls, but significance is not reached when appropriate statistical corrections are made. Ethnological differences can lead to sampling biases; a purported increased frequency of HLA-Bw16 in Ashkenazi Jewish bipolar patients is negated when ethnologically similar controls are used. The transmission of HLA alleles in 9 families with at least 2 generations of affective illness revealed independent assortment, and nonlinkage to either locus A or B was demonstrated using a multigenerational method of linkage analysis. The nonreplicability of the HLA association studies and the failure to demonstrate linkage of the HLA loci with affective illness in this study suggest that the HLA system may not be related to the development of affective illness. Further analyses are necessary.
