rs356219, a tagging SNP in the SNCA gene for a Parkinson's disease associated haplotype, predicts the amount of SNCA (alpha-synuclein) mRNA found in post mortem substantia nigra and cerebellum brain tissue. replicates the association of rs356219 with late-onset Parkinson's disease, calculating an odds ratio of 1.3 (CI: 1.13 - 1.5, p=2x10e-4) per rs356219(G) allele among the 1145 patients from northern Spain studied. {{PMID Auto |PMID=21060011 |Title=SNCA Variant Associated With Parkinson Disease and Plasma {alpha}-Synuclein Level |OA=1 }} Linkage disequilibrium patterns and tagSNP transferability among European populations.
