23andMe Has Teamed Up with the Michael J. Fox Foundation to Help Research for Parkinson's

Parkinson’s disease was primarily believed to have no genetic basis before. However, during the Human Genome Project, they traced Parkinson’s to a specific gene that was prevalent in patients in North America and Europe. This was the LRRK2 gene. After its discovery, the gene is now used as a genetic marker for the risk of Parkinson’s disease. This marker is also seen to cause a greater risk to other ethnicities. There currently is no explanation for the disease, but research is still ongoing about this discovery.
