A charity supporting Australians impacted by, or living with genetic, heritable and / or rare connective tissue disorders.



CTDNA: Empowering Australians Impacted by Heritable Connective Tissue Disorders (HCTD) through advocacy, education, and collaboration.

Join our network of advocates, healthcare professionals, and researchers to improve care and support for those with HCTD. Together, we’ll break down barriers, shorten diagnostic journeys, and enhance research efforts for a brighter future.


Thousands of Australians live with genetic, heritable and / or rare connective tissue disorders; also referred to as; heritable connective tissue disorders (HCTD). Ehlers-Danlos syndrome, Marfan syndrome, Loeys-Dietz syndrome and Stickler syndrome are just a few of the many dozens of identified HCTD.

Connective Tissue Disorders Network Australia (CTDNA) is the collaborative effort of people both living with, and / or caring for those with HCTD. Individuals are often both; a patient, and a carer. 

CTDNA seeks to establish a national network of lived experience advocates, healthcare professionals and researchers with an interest in HCTD. A network of like minded individuals coming together to better the care and management of Australians impacted by HCTD.

Goals of CTNDA


Supporting an educated healthcare workforce


Encouraging informed patients
