Okur-Chung neurodevelopmental syndrome (CSNK2A1-related condition)
Our researchers are investigating speech and language in individuals with OCNDS (also known as CSNK2A1-related neurodevelopmental syndrome). By improving our understanding of speech and language abilities, we hope to improve prognoses, better identify those in need of speech therapy and develop more targeted therapies.
We are looking for individuals:
• With a pathogenic or likely pathogenic CSNK2A1 gene variant
• Aged 6 months to adulthood
• Who are speaking or non-speaking
What is involved?
• Complete online surveys about speech, language, communication, health and medical history
• Complete a speech assessment (where able) either in-person or via telehealth
This is an international study and surveys are available in English, French, Dutch, German, Spanish, Portuguese, Italian, Polish, or Chinese.

Research into mental health outcomes in individuals with NRXN1 deletions
Researchers from the NHMRC Centre of Research Excellence - Translational Centre for Speech Disorders are currently investigating factors that influence mental health outcomes in individuals and their families with NRXN1 deletion. This work is performed in collaboration with Thomas Bourgeron, Louise Gallagher and other Chief Investigators on the EU-Horizon grant on ‘Risk and Resilience in Mental Health Conditions’.
Genetically, NRXN1 deletion is known to play a significant role in neurodevelopment and disruptions of this gene can lead to conditions such as autism spectrum disorder, attention deficit/hyperactivity disorder, intellectual disability, language difficulties and subtle movement problems. Some individuals with NRXN1 deletion are at a higher risk for adverse mental health outcomes. Currently, little is understood regarding which factors contribute to positive versus more challenging mental health outcomes in individuals with NRXN1 deletion. Learning more about the mental health in individuals with NRXN1 deletion will help us identify people who may be at increased vulnerability for mental health challenges and allow us to develop more targeted treatments.
If you are interested or know someone who may be interested, please do not hesitate to contact us at NRXN1@mcri.edu.au or complete the following link https://redcap.link/RADIANT. For more information, please see our flyer.
Studies in specific genetic conditions
Researchers from the NHMRC Centre of Research Excellence - Translational Centre for Speech Disorders are currently investigating speech and language presentations in several genetic conditions. This knowledge will help us learn more about diagnosis of these conditions, prognosis for speech and language outcomes and assist in tailoring therapies and supports for individuals and their families. Research is currently being conducted in the following genetic conditions:
Okur-Chung neurodevelopmental syndrome (CSNK2A1-related condition)
