HLA-A and cancer: mKRAS-specific T cells restricted to HLA-A*03:01 and HLA-A*11:01 were sorted and sequenced because these alleles are very common in the United States (~20% and 10% of the population, respectively) and at least ~21,000 newly diagnosed patients/year have KRAS G12V/G12D cancers that express either allele (Pearlman et al. 2021).
