From: Clustered protocadherins methylation alterations in cancer
Discovery set unsupervised hierarchical clustering analysis based on the average methylation β value for the two aberrantly methylated CGIs. Heatmap obtained by UHC of 50 BTC samples and 10 matched normal samples. The UHC analysis clearly separated one group of sole tumours and another group including normal and tumoral samples. To the right of the heatmap further information are reported: histology, localization and grade. BTC, biliary tract cancer
