Approximately 20 years ago clinicians made a striking observation: grandfathers of children with fragile X syndrome frequently displayed Parkinsonian-like phenotypes. Subsequent studies showed that a premutation of the FMR1 gene was the cause for this, as this results in the formation of aberrant proteins aggregates, cell damage and a disorder now called the Fragile X Tremor Ataxia Syndrome.

We investigate how the gene mutation and protein aggregates are damaging neuronal cells, particularly in determining their effects in brain regions that control cognitive and emotional behaviours. We have already shown that the damage is partially reversible, and are currently searching for suitable pharmacological interventions
