N2 - Heterozygosity at human leukocyte antigen ( HLA ) loci may improve lung cancer immunosurveillance by increasing recognition of the tumor by the immune system. Previous studies utilizing data from population-level biobanks, such as the United Kingdom Biobank and FinnGen, have identified an association between germline HLA class II ( HLA- II) heterozygosity and reduced lung cancer risk in smokers. In the present study, we evaluate the association between HLA heterozygosity and lung cancer in a large case-control study (15,302 cases and 14,580 controls) with imputed HLA allele-type information, comparing differences in HLA heterozygosity between smokers and non-smokers, among lung cancer subtypes, and at 2- and 4-digit HLA allele resolution. We identify a strong protective association of HLA -II heterozygosity in smokers compared to non-smokers, particularly at the HLA-DPB1 and HLA-DPA1 loci, and provide subtype-specific resolution. Finally, analysis of the additive effects of HLA allele heterozygosity in smokers identified significant associations with several 4-digit HLA alleles, including HLA-B∗08 : 01 , HLA-A∗01 : 01 , HLA-C∗07 : 01 , HLA-DQA1∗05 : 01 , HLA-DRB1∗03 : 01 , and HLA-C∗03 : 04 . Our study provides additional evidence, with added histologic subtype information, that germline HLA -II heterozygosity is inversely associated with lung cancer risk.
