In21, it has been proposed that the C6orf97 gene, the highest scoring gene of \documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$Z_{\textrm{BRCA}}$$\end{document}ZBRCA, might play important roles not only in carcinogenesis but also in the progression of breast cancer patients toward a more aggressive phenotype. The gene discussed is CCDC170; the disease is breast carcinoma.
