I did a little googling last night for this. Variants of the LRRK2 gene has also been associated with Parkinson's in Ashkenazi Jews. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene&cmd=Retrieve&dopt=Graphics&list_uids=120892 A couple other genes are also linked to Parkinson's in Chinese populations, SNCA and CHRNA4 came to the top of the list.
