Center for Translational Research at Rush University Medical Center in Chicago.  She established the Fragile X Clinic and Research Program at Rush University Medical Center in 1992 and has provided care to over 800 patients with fragile X syndrome (FXS). She conducts research on FXS, including genotype-phenotype, molecular, biomarker, outcome measure, and natural history studies, and clinical trials. She has expanded this clinical and translational work to other neurogenetic diseases in the past 10 years, including work on PMS, NPC, Angelman syndrome, Rett syndrome, Batten’s disease, PKAN, and creatine transport deficiency. She has led the effort to develop new targeted treatments for FXS and other genetic neurological diseases, including antisense oligonucleotides and gene therapy, and has implemented novel trial designs, including N-of-1 trials.
