Immunogenetic Association of 127 Human Leukocyte Antigen (HLA) Alleles with 30 Cancers in Continental Western European Countries

Abstract

Human leukocyte antigen (HLA) genes have been associated with susceptibility and protection against a number of cancers. Here we used an immunogenetic epidemiological approach to evaluate the overall influence of 127 HLA Class I and II alleles on 30 types of cancer. We found a preponderance of protective alleles (negatively correlated with cancer prevalences), especially for HLA Class I. Of the 30 cancers investigated, 13 were associated with mostly protective HLA effects whereas only 2 were associated with mostly susceptibility HLA alleles. Taken together, these findings highlight the broad influence of HLA on cancer and the complexity of HLA-cancer associations.
