INS and Parkinson disease: Considering the similar pattern of linkage disequilibrium in JPT and CHB with similar frequency of mutant allele (both 6.2% according to HapMap), there is a high chance that similar association between rs2046932 and PD can be found in CHB, however, most likely rs2046932 is not the causal variant and can be eliminated from functional analysis due to the negligible level of LD in CEU and INS (Figure 1).
