Notes
rs16851009 increases susceptibility to Parkinson's disease 1.84 times for carriers of the T allele Genomewide association, Parkinson disease, and PARK10. No evidence for association with Parkinson disease for 13 single-nucleotide polymorphisms identified by whole-genome association screening. A case-control association study of the 12 single-nucleotide polymorphisms implicated in Parkinson disease by a recent genome scan.
