A significant amount of research has been conducted on the over expression of the CTNNB1 gene and its connection to cancer. Researchers have published over 25,000 studies that have revealed the biology of the Wnt signaling pathway. 

However, very little research has been done on the gene as a result of a de novo mutation that results in too little beta catenin production. The underproduction of beta catenin causes CTNNB1 syndrome which our children are affected by. We have compiled some information from the following researchers on CTNNB1 gene mutation.
