PTPN1 and colorectal cancer: Using cbioportal, we further analyzed the TCGA colorectal cancer dataset [28], revealing an alteration in the PTPN1 gene (e.g. amplification, mutation, upregulation) in 45.1% of cases (Figure S1C) and a trend towards worse survival for patients with alterations in the PTPN1 gene (Figure S1D).
