There are also suggestive clusters of late-stage insertions surrounding the MHC Class I components H2-T24/T23/T9/T22/BI/T10/T3/Gm7030 (equivalent to the HLA-E locus) and the MHCII alpha/beta chains H2-Oa/H2-DMa/H2-DMb (equivalent to the HLA-DOA/HLA-DMA/HLA-DMB region), suggesting roles for both classical and non-classical MHC components in MuLV lymphoma progression. This evidence concerns the gene HLA-E and lymphoma.
