Polycomb group genes (PcGs) are epigenetic effectors implicated in most cancer hallmarks. The mutational status of all PcGs has never been systematically assessed in solid tumours. We conducted a multi-step analysis on publically available databases and patient samples to identify somatic aberrations of PcGs. Data from more than 1000 cancer patients show for the first time that the PcG member PHC3 is amplified in three epithelial neoplasms (rate: 8–35%). This aberration predicts poorer prognosis in lung and uterine carcinomas (P<0.01). Gene amplification correlates with mRNA overexpression (P<0.01), suggesting a functional role of this aberration. PHC3 amplification may emerge as a biomarker and potential therapeutic target in a relevant fraction of epithelial tumours.
