Synonymous mutations inside the coding region, which do not alter the amino acid chain, are usually considered to have no effect on the protein. However, in the recent years it was shown that they may regulate expression levels via various mechanisms, suggesting that they may also play an important role in tumorigenesis.

In the current study, we report for the first time cases where cancerous synonymous mutations inside the coding regions of the gene BCL2 are under selection in germinal center B-cell (GCB) lymphoma patients.

We provide various lines of evidences that suggest that these mutations contribute to the cancer cell survival via improving the expression levels of anti-apoptotic BCL2 protein.
