This week we are going to continue with the focus on FAST’s 4 Pillars in the Roadmap to a Cure 2.0, highlighting Pillar 2 – Fix Dad’s Gene.
To quickly reiterate, everyone has both a mom (maternal) and dad (paternal) copy of UBE3A in the brain and the paternal copy is silenced due to an antisense transcript that binds to the dad’s copy and prevents the process required to produce UBE3A protein.
This is fine when the maternal copy can produce functional UBE3A, but in the case of Angelman syndrome where maternal UBE3A does not, a promising approach towards treating AS lies in turning on, or reactivating, paternal UBE3A.
This Pillar 2 – Fix Dad’s Gene encompasses all work being done to reactivate the paternal UBE3A copy via antisense knockdown in the brain.
We want to feature some of the exciting work Dr. Yong-Hui Jiang presented at the 2022 FAST Global Science Summit.
In his talk, Dr. Jiang discussed a novel CRISPR editing approach packaged in chemically engineered ribonucleoproteins to knockdown the paternal antisense transcript and reinstate paternal expression, using a mouse model of AS.
