Association and haplotype analysis of GBA mutation ( GBA N370S) and flanking SNPs in 3 datasets. a) Single point analysis plus 2 haplotype analyses: with vs. without the mutation in Ashkenazi Jewish. b) Single and haplotype analyses without mutation in NINDS. c) Single and haplotype analyses without mutation in CIDR/Pankratz et al 2009. 2-SNP sliding window, the strongest p-value was present from the exhaustive search.
