Tumours with a low MITF expression showed an increase in the numbers of CD3D (p = 0.048), CD8A (probe 3: p = 0.01), and CD68 (two probes, p = 0.001 and p = 0.004) cells, as well as a higher expression of HLA-A (three probes: p = 0.003, p < 0.001, and p = 0.002) and HLA-B (p = 0.004). The gene discussed is HLA-A; the disease is neoplasm.
