Our Changing World: The PINK1 Clue in Parkinson's Disease
Researchers have identified a specific genetic variant in the PINK1 gene that is linked to higher rates of Parkinson's disease among Pasifika populations in New Zealand. This discovery allows for more targeted medical treatments for a condition that was previously poorly understood.
Why it matters
Understanding the genetic drivers of Parkinson's in specific ethnic groups can lead to earlier diagnosis and personalized therapeutic interventions.
A form of Parkinson's disease once considered rare is far more common in Pacific communities than previously recognised. Researchers estimate more than 400 Pasifika people in New Zealand could be living with a genetic form of the condition linked to a variant in the PINK1 gene.

The condition, known as PINK1 Parkinson's disease, is being researched in Aotearoa and the Pacific after studies revealed unusually high rates of the variant, particularly in Samoan and Tongan populations.
Unlike most forms of Parkinson's disease, where the underlying cause remains unclear, researchers know exactly what drives PINK1 Parkinson's disease, creating new opportunities for more targeted treatments.
