A study links a SNCA gene mutation to Parkinson’s, enabling early detection years before symptoms via reprogrammed brain cells.
A new study by University of Wollongong’s Professor Lezanne Ooi focuses on a genetic mutation in the SNCA gene linked to Parkinson’s disease, which causes harmful protein buildup in brain cells.
Using reprogramming techniques, researchers are transforming human cells into affected brain cells to study early disease processes, aiming to enable diagnosis years before motor symptoms appear.
Non-motor signs like loss of smell may precede movement issues by up to two decades, offering a window for early intervention.
The research could improve lab models, accelerate treatment development, and help families with hereditary risk avoid delayed diagnoses, as seen in cases like Amelia Dowe’s mother, whose later diagnosis led to improved mobility and confidence through treatment and lifestyle changes.
