#Didyouknow As well as investigating the genetics of #stuttering, our study team are involved in research into other speech disorders, and several neurological conditions.

Here is one example of some of this exciting other work from study investigator @MelanieBahlo ! #scicomm https://t.co/gCKr7aEfB8

Walter + Eliza Hall @WEHI_research
A decades-long global study involving WEHI bioinformaticians Mark Bennett @HaloomRafehi and @MelanieBahlo revealed two new gene mutations that cause a rare type of #epilepsy.

The research was published in @NatureComms in December.

About the 'Genetics of Stuttering Study’

The 'Genetics of Stuttering Study’ aims to pinpoint the genes that predispose individuals to stuttering, which could revolutionise future research into the causes, treatment and prevention of the disorder.

Stuttering or stammering affects verbal communication – particularly the rhythm or flow of communication.

Although the exact cause of stuttering is yet to be determined, genetics does play a role in stuttering, and a number of genetic variants having been identified to date.

The study involves 15 investigators at eight sites in Australia, the UK, the USA and The Netherlands. 

Study researchers are working to recruit 3,000 volunteers from Australia, aged 7+ with a history of stuttering (past or present).

Please see http://www.geneticavanstotteren.nl/ for more information about recruitment in the Netherlands and Belgium. We will be starting to recruit from other countries very soon - watch this space!

Participating in this study could make a genuine contribution to the understanding of stuttering.

How can you help?

If you currently live with, or have a history of stuttering, we encourage you to volunteer for our groundbreaking research study by completing the 10 minute core component of our online survey. Depending on your responses to our survey, you may be asked to donate a saliva sample.

To help us meet our target of 3,000 participants by 31 December 2020, volunteer for our study today
