We used the cBioPortal online tool to analyze correlations among altered S100 family genes in COAD specimens and pinpointed 126 specimens (126/379, 33%) showing abnormally expressed S100 genes related to COAD, of which 31 to 69 samples exhibited two or more abnormally expressed S100 genes (see Figure 6(a)). Here, S100A1 is linked to colon adenocarcinoma.
