In a more recent study looking at DNA copy number of cervical adenocarcinomas, it was found that despite more than 50% of patients had chromosome 17q copy number gains, only 9% (2 out of 22) of these tumors showed an HER-2/neu protein over-expression at the level of 2+ with the Hercep test. The gene discussed is ERBB2; the disease is cervical adenocarcinoma.
