The results of the TISIDB analysis suggested that AHNAK2 has positive correlations with 28 tumor-infiltrating lymphocyte (TIL) types (Figure 4F) and human leukocyte antigens (HLAs) (Figure 4G) across human cancers, which is particularly significant in THCA (papillary thyroid carcinoma in TCGA). Here, HLA-S is linked to differentiated thyroid carcinoma.
