Comprehensive Summary
The conception of the neurodegenerative disorder known as Parkinson’s disease is heavily dependent on a series of genetic mutations in certain genes, one of them being the PINK1 gene. PINK1 plays a key role in protection from stress-induced issues in the mitochondria. This study looked at single base pair variations (SNPs) in the PINK1 gene along with the type and intensity of change the mutation brought, both in the short and long term. Ultimately, they found 5 different mutations that proved to be “high-risk” candidates for disrupting PINK1 function.
Outcomes and Implications
This work matters due to the lack of therapies and/or permanent cures for Parkinson’s disease. By starting with a specific mutation in a single gene, this study is opening the door for endless possibilities in future research in regards to potential targets for new drugs, and, on a more fundamental scale, how exactly SNPs contribute to Parkinson’s.
