"This discovery is a seminal finding in cancer biology that confirms AKT1 as an oncogene in breast, colorectal and ovarian cancer. The mutation alters the electrostatics of binding pocket in the pleckstrin homology domain, the portion of the enzyme that docks with phospholipids on the cell membrane," said Kerry L. Blanchard, PhD, MD, Executive Director, Discovery Biology Research, Eli Lilly & Company".
Although this isn't specifically TN it is interesting that they have found another mutation to study.
