By thinking of Parkinson’s not as just one disease but as a collection of conditions with similar symptoms driven by different factors, subtyping people with Parkinson’s will improve the outcome of clinical trials and help accelerate drug development to stop disease progression.
Subtyping is the process of identifying the characteristics (phenotype) of an organism, which result from the interaction of its genetic makeup (genotype) and environment.
There are over 20 genes linked to Parkinson’s with many more associated as risk factors.
