The gene responsible for PARK6 Parkinson's disease, PINK1, does not influence common forms of parkinsonism.
Mutations in the PINK1 gene (PARK6), a putative serine-threonine kinase, cause autosomal recessive Parkinson's disease. PINK1 functions as a protein kinase and confers protective effects in the mitochondria, where it is primarily located. We assessed in a population of European ancestry whether common genetic variation in this novel gene influences nonmendelian forms of Parkinson's disease. We defined the linkage disequilibrium structure of PINK1 and used this to identify a set of tagging single nucleotide polymorphisms that we estimate will efficiently represent all of the common DNA variation in the entire gene. Genotyping these tags in a set of 576 Parkinson's disease patients and 514 controls did not demonstrate a case-control partition for allele or for haplotype and thus provides evidence against the existence of a common functional variants in PINK1 that has a strong influence on PD risk.
