Our findings indicate a positive correlation between tumor‐intrinsic IL4I1 expression and the expression of HLA‐A/‐B/‐C, B2M, and genes associated with CTL activation (GZMB, GZMA, CD8A, IFNG) in melanoma patients (Figure 3H; Figure S3D,E, Supporting Information). The gene discussed is IL4I1; the disease is melanoma.
