Most of what is known about the genetics of Parkinson's disease comes from people of European ancestry — a gap that limits how well genetic tests and future therapies will work for everyone else. The largest multi-ancestry genetic study of Parkinson's disease to date, published in The Lancet Neurology, analysed genome and exome sequencing data from more than 99,000 people across 11 genetically inferred ancestries. The study identified causal and risk variants whose frequency differs substantially between populations; roughly 29% of participants with Parkinson's disease came from under-represented, non-European ancestries largely absent from earlier research. Ancestral diversity in Parkinson's disease research is needed to improve diagnostic accuracy and help ensure equitable access to emerging genetically informed therapies.
