Unlike the healthy genome, in which changes in gene expression are carefully controlled through transcription factors, the cancer genome adapts through the duplication of CD1C, CFHR3, FOXP2, MDFIC, RALYL, CSMD3, SAMD12-AS1, MAL2, and OR52N5, and loss in the coding regions of ADAM5, LOC400927, APOBEC3B, RPL3, MGAT3, SLC25A17, EP300, L3MBTL2, SERHL, POLDIP3, A4GALT, and TTLL1 genes. The gene discussed is A4GALT; the disease is cancer.
