By Vicki Jackson | Dec 23, 2019

2019 has been a busy year for the Genetics of Stuttering Study! As the year draws to a close, we thought it a good time to provide an update on how the study is progressing, and our plans into the new year.

Spotlight: Participant Rich talks about his experiences with stuttering

By MCRI | Nov 12, 2019

Rich Stephens talks about his experiences with stuttering, and the power of not feeling alone. He feels strongly that “stuttering should never be a taboo subject”. He believes that “to understand anything you need to start at the beginning. Which is why The Genetics of Stuttering Study is so important for the future generations of people who stutter.”

Sorry we have been a bit quiet recently - like everyone we have been busy adjusting to new ways of living and working.

The good news is, most aspects of the study are continuing as normal, including recruitment! 💪 #research #positivity

Stay safe everyone!! https://t.co/QRP2O1ecQf

Here at @MCRI_SpeechLang, we are very luck to have comedian @MrJoshEarl working with us to advocate for people with a number of speech disorders, including #apraxia of speech and #stuttering.

Check out this video from him over on Facebook:

Orientation sessions are happening at many Australian universities this week. This can be an exciting, but challenging time, not least for those who experience #stuttering.

@stammer has some helpful tips: https://t.co/45HpUu8Zrg

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
