Research

Dr. Paul Hagerman is a molecular geneticist with a principal interest in understanding the basis for neurodevelopmental and neurodegenerative diseases. In particular, the Hagerman lab has made a number of important observations related to the mechanism of gene expression of the fragile X (FMR1) gene. Mutations of the FMR1 gene give rise to fragile X syndrome, the leading heritable form of mental impairment and autism, and premutation-related disorders, such as fragile X-associated tremor/ataxia syndrome (FXTAS). With features of Parkinsonism and dementia, FXTAS represents a model system for understanding the basic cell mechanisms underlying more common disorders such as Parkinson’s and Alzheimer’s diseases.
