Nearly One-Third Of Participants In Global Parkinson’s Genetics Study Were From Under-Represented Populations

Researchers reported that 26.4% of Parkinson's disease (PD) cases in a large multi-ancestry genetics study were from non-European and non-Ashkenazi Jewish populations. Overall, nearly one-third (29%) of all study participants, including both people with PD and healthy controls, were from these under-represented populations. The researchers said expanding ancestral diversity in Parkinson's disease research could improve diagnostic accuracy and enhance understanding of disease mechanisms across populations, noting that most previous PD genetic research has focused on European and Ashkenazi Jewish populations.
