An AS 15q11-13 deletion mouse model


Existing mouse models have a deletion of only UBE3A, which models a UBE3A mutation.  This project will develop two new mouse models to determine how the other genes missing in the AS deletion (as opposed to UBE3A mutation) contribute to the severity of the disorder. 

There will be two different models developed: 

  1. One will include UBE3A, GABRB3, GABRA5, GABRG3, ATP10A, HERC2, OCA2,  CYFIP1, NIPA1, and TUBGCP5.  These are the genes that are deleted in individuals with Class I or Type I AS deletions. 
  2. The second mouse is missing all of those genes except for UBE3A. 

This study hopes to answer two major questions. 

  • Can we use this mouse model to better understand the deficits in individuals with AS due to deletion? 
  • What phenotypes might remain if we were to totally restore UBE3A using therapeutic approaches?
