About the 'Genetics of Stuttering Study'

Researchers from the NHMRC Centre of Research Excellence in Speech and Language are calling for 3,000 participants aged seven and above with experience of stuttering (past or present) to volunteer for the Australian and New Zealand arms of world’s largest ever ‘Genetics of Stuttering Study’.

The study aims to pinpoint the genes that predispose individuals to stuttering. This could revolutionise future research into the causes, and biology of stuttering.

Volunteers must be:

  • Aged seven and above
  • Currently stutter or have a history of stuttering.

Not based in Australia or New Zealand?

No problem - you are very welcome to sign up to our study; however, depending where you live, we may not be able to collect a saliva sample for genetic analysis just yet. Even if you are not able to provide a saliva sample, the information you provide via the questionnaire will still be valuable to our ongoing work to better understand the experiences of people who stutter.

The Dutch arm of this study is now recruiting participants in the Netherlands and Belgium! Please see http://www.geneticavanstotteren.nl/ for more information.

We will be starting recruitment drives in other countries very soon - watch this space!
