GGT1 has a suggested function in pancreatic carcinogenesis [42], whereas NCOR1 is part of a corepressor complex with histone deacetylase 3 (HDAC3) and may act as an oncogene in thyroid cancer [43,44], while ERCC5 polymorphisms were reported in breast cancer [45,46]. The gene discussed is GGT1; the disease is breast carcinoma.
