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). This evidence concerns the gene HLA-S and thyroid gland papillary carcinoma.
