On page 843, in the section on Sox2 it was stated that the Ysb and Lcc mutations were generated by ENU treatment, which is incorrect. In fact, Ysb was generated through transgene insertion, whereas Lcc was caused by X-ray irradiation.

On page 849, the highlighted statement starting “A seminal study...” should be attributed to reference 86, rather than reference 85.
