Genotype‐phenotype correlation of CTNNB1 mutations reveals different ß‐catenin activity associated with liver tumor progression
Sandra Rebouissou, Andrea Franconi, Julien Calderaro, Eric Letouzé, Sandrine Imbeaud, Camilla Pilati, Jean‐Charles Nault, Gabrielle Couchy, Alexis Laurent, Charles Balabaud, Paulette Bioulac‐Sage, Jessica Zucman‐Rossi – 14 May 2016 – CTNNB1 mutations activating ß‐catenin are frequent somatic events in hepatocellular carcinoma (HCC) and adenoma (HCA), particularly associated with a risk of malignant transformation. We aimed to understand the relationship between CTNNB1 mutation types, tumor phenotype, and level of ß‐catenin activation in malignant transformation.
