Efficient presentation of mutant peptide fragments by the human leukocyte antigen class I (HLA-I) genes is necessary for immune-mediated killing cancer cells. According to recent reports, patient HLA-I genotypes can impact efficacy immunotherapy, and somatic loss heterozygosity has been established as a factor in immune evasion. While global deregulated expression also reported different tumor types, role allele-specific - that is, preferential RNA specific alleles not fully characterized...
