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 is considered a disability that 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 10 investigators at eight sites in Australia, the UK and The Netherlands.

Recruitment closes December 31, 2019. Study researchers are working to recruit 3,000 volunteers aged 7+ with a history of stuttering (past or present) into the study.

Participating in this study could make a genuine contribution to solving this disorder.
