Summary
Fragile X syndrome (FXS) is a common heritable cause of intellectual disability and co-morbid autism, caused by epigenetic silencing of the FMR1 gene. This will be the world’s largest FXS mutation prevalence study conducted in 100,000 newborns using a novel test targeting epigenetic changes, and will also explore the prognostic outcomes, costs and benefits associated with FXS newborn screening, providing conclusions regarding expanding the current newborn screening in Australia to include FXS.

Summary
Intellectual disability is frequent in the population, with as many as 1 in every 50 people in the world directly affected. ARX is one of the most frequent genes mutated in X chromosome-linked intellectual disability. Our study will specifically address the functional impact of these mutations in ARX using cell models relevant to the brain. We will also examine the contribution of other genetic changes to explain the very different symptoms seen in patients with the same gene mutation.
