Researchers from the 成人大片 have identified the gene that is the most common genetic cause of cerebral palsy, increasing the chances of finding better treatments for the debilitating disease.

The study 鈥� published in , the official journal of the American College of Medical Genetics and Genomics 鈥� also established a laboratory test for the gene involved that provides greater certainty of a genetic diagnosis.

鈥淯sing the most commonly affected gene associated with cerebral palsy as a leading example, we showed that assignment of cerebral palsy diagnosis is inconsistent,鈥� said senior author Mark Corbett, from the Australian Collaborative Cerebral Palsy Research Group at the Robinson Research Institute and Neurogenetics Research Program at the University鈥檚 Adelaide Medical School.

鈥淎n inconsistent diagnosis may affect access to services relevant for treatment and support for those living with cerebral palsy.

鈥淭he myth that cerebral palsy is due to difficulties at birth is often being rejected when there is access to modern genetic testing.鈥�

Each of the individuals involved in the study had a genetic variant in a gene called CTNNB1, which can cause a neurodevelopmental disorder with spastic diplegia and visual defects. It is the most common monogenic (single mutation) cause of cerebral palsy.

鈥淲e found six times the number of people were genetically diagnosed with the disorder than is typically quoted in previous studies,鈥� Corbett said.

鈥淎 confirmed genetic diagnosis allows families to create specific healthcare plans and brings people living with the disorder together through existing social and charitable networks.

About 33 per cent of cerebral palsy cases are caused by a person鈥檚 genetics.

An estimated 34,000 people in Australia, and 17 million people worldwide, are living with cerebral palsy. One in 500 Australian babies are diagnosed with cerebral palsy, which is a physical disability that affects movement and posture.

PhD candidate Sayaka Kayumi at the 成人大片 was the lead author of this two-year study, out of an international team from Australia, France, the Netherlands, Spain, the United Kingdom and the USA. Emeritus Professor Alastair MacLennan AO, from the 成人大片鈥檚 Robinson Research Institute, and Jozef Gecz, Senior Principal Research Fellow at the 成人大片鈥檚 Adelaide Medical School, were co-senior authors.

The research paper is titled 鈥� 鈥淕enomic and phenotypic characterization of 404 individuals with neurodevelopmental disorders caused by CTNNB1 variants.鈥�
