This SNP, which is in linkage disequilibrium with the SCARB2 gene, was found in association with PD in two large multi-ethnic genome-wide association studies (OR=0.84; P=7.6×10−10 and OR=0.907; P=2.95×10−11)5,9 and in a German association study (OR=0.86; P=0.02).6 However, the association was not replicated in a Chinese10 or a Greek cohort,11 likely due to either population differences or insufficient power. This evidence concerns the gene SCARB2 and Parkinson disease.
