Figure 7. Genomic aberrations of MHC class I genes in NPC.
(a) A summary of genetic alterations in MHC class I genes, including HLA-A, HLA-B, B2M and NLRC5. (b) NPC patients with MHC class I gene mutations have poorer overall survival and disease-free survival (P=0.003, and P<0.0001, respectively; Log-rank test on 70 primary NPC cases).
