In addition to the abovementioned genes, some genes play an important role in the progression and prognosis of other tumors as well, such as AURKB in clear cell renal cell carcinoma (Wan et al., 2019) and gastric cancer (Nie et al., 2020), MSX1 in melanoma (Heppt et al., 2018) and breast cancer (Yue et al., 2018), ERP29 in osteosarcoma (Chaiyawat et al., 2019), and MT1F in gastric cancer (Lin et al., 2017). The gene discussed is MSX1; the disease is breast cancer.
