Beside luminal B BC, high expression of ZNF703 was also found by immunohistochemistry in a third of TNBC patients [42] as well as in other cancers such as gastric, colorectal, head and neck cancers, non-small cell lung, cholangiocarcinoma, papillary thyroid carcinoma (PTC), medullary thyroid carcinoma (MTC), hepatocellular carcinoma (HCC) and ovarian cancer [43,44,45,46,47,48,49,50,51]. This evidence concerns the gene ZNF703 and medullary thyroid gland carcinoma.
