In a study using cancer genomics data sets derived from over 5000 tumour samples from 20 cancer studies to identify cancer types with significant amplification of BCL-XL (The cBio Cancer Genomics Portal [70]), both colorectal cancer and cervical cancer demonstrated the highest percentage of BCL-XL gains and amplifications across all cancer types analysed [71]. The gene discussed is BCL2L1; the disease is colorectal cancer.
