On the other hand, SOX10 appears to have a more direct correlation to low-ER tumors (Fig. 5F), with high (> 10% of tumor cells) expression of SOX10 observed in 47.47% of low-ER tumors, while only 1 of the luminal B tumors (4.76%) expressed high levels of SOX10. The gene discussed is SOX10; the disease is neoplasm.
