October 2019: Dr. Stephanie Joy Bouley has received the Dorothy and Spiro Latsis Fellowship in Neurofibromatosis Research from Boston Children’s Hospital. With this two-year fellowship, Dr. Bouley will continue her work on identifying unique network signatures associated with NF1 loss in plexiform neurofibromas. Congratulations Stephanie!

September 2019: Dr. Jim Walker recently spoke at the annual NF Conference hosted by the Children’s Tumor Foundation in San Francisco, California. Dr. Walker’s talk, entitled “Modeling NF1 in Drosophila” kicked off the Animal Models session of the four-day conference and focused on the novel insights the fruit fly Drosophila has provided into NF1 biology.

May 2019: Dr. Jim Walker was one of two recipients to receive funding from the Children’s Tumor Foundation in the form of a NF1 Gene Therapy Initiative Award. Dr. Walker’s project focuses on investigating the feasibility of using genome editing (both CRISPR-based homology-directed repair and base editing) as a therapeutic approach to correct three pathogenic NF1 mutations in cultured human Schwann cells. We will capitalize on recently developed CRISPR/Cas9 and Cas12a variants, which increase the targeting range, activity, and fidelity (reducing off-targets) of gene-editing in collaboration with Dr. Ben Kleinstiver of the Center for Genomic Medicine at MGH.

March 2019: Research Associate Brittany Leger recently gave a Plenary Platform Presentation at the Genetics Society of America 60th Annual Drosophila Research Conference held in Dallas, Texas. This work is a result of a collaboration between the Walker and Saxena labs from the Center for Genomic Medicine at MGH, as well as with the Schreiber lab at the Broad Institute and focuses on the effects of ALG10 mutations and protein N-glycosylation on sleep and seizure phenotypes in a Drosophila model of ALG10 loss. Well done Brittany!
