Summary
Complete loss of ACTN3 is normal and occurs in 1 in 5 people world-wide. While it does not cause disease, loss of ACTN3 results in ~10% reduction in muscle mass and strength. This has tremendous impact not only on the success of elite athletes but also the quality of life in people who are already frail. Precisely how ACTN3 affects muscle mass is unclear. Understanding this will help identify the patients who are at greater risk of muscle wasting and also the therapies that will best treat them.
Investigating The Pathogenic Mechanism Of Mutations In IQSEC2 Causing Non-syndromic Intellectual Disability.

Summary
Intellectual disability is frequent in the population, as many as 1 in every 50 people in the world affected. Mutations in IQSEC2, an X-chromosome gene, cause intellectual disability. We will screen 1000 families with this disability for mutations in IQSEC2, building the picture of disease symptoms, contributing to informed genetic counselling. We will investigate functional impacts of these mutations in neuronal cultures, increasing our understanding of the causes of intellectual disability.
