The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The Effects Of ACTN3 R577X On Muscle Wasting And Repair, And Response To Therapy
Funder
National Health and Medical Research Council
Funding Amount
$1,066,054.00
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.
Approaches To Therapy For The Skeletal Muscle Actin Diseases
Funder
National Health and Medical Research Council
Funding Amount
$912,078.00
Summary
We have shown that errors in a crucial muscle protein called actin cause muscle diseases that affect newborn children. These diseases are mainly very severe, causing death within the first year of life. Currently there is no cure. This project will investigate possible therapies for these diseases, such as viral delivery of a normal version of actin and finding a drug to overcome the weakness. Successful outcomes will crucially bring treatment closer for the patients.
