In October of 2015 she joined to Board of Directors as a Scientific Director for the Foundation for Angelman Syndrome Therapeutics (FAST), and in March of 2016 became the Chief Science Officer for the Foundation. Dr. Berent helped to spearhead the development of a pre-competitive biomarker and outcome measure consortium in order to bring patient focused outcome measures forward for human clinical trials (Angelman Syndrome Biomarker and Outcome Measure Consortium-ABOM) and Co-Founded the International Angelman Syndrome Research Council (INSYNC). Through FAST, Dr. Berent collaborated with a consortium of scientists to encourage translational research opportunities, in order to help bring novel genetic therapies forward toward human clinical trials. Through this work, with the foundation, Dr. Berent co-founded GeneTx Biotherapeutics, a company singularly focused to advance an antisense oligonucleotide (ASO) therapy through IND enabling studies and a phase 1/2 clinical trial. Dr. Berent currently serves as the Chief Operating Officer of GeneTx Biotherapeutics, who partnered with Ultragenyx Pharmaceuticals in August of 2019.
