{{PMID|18205889}} [[Parkinson's disease]] The risk alleles for each SNP identified from conditional logistic regression, [[rs1721100]] C, [[rs1721082]] T and [[rs1799836]] A, are consistent with previous reports.
Significant interaction between this [[FGF20]] SNP and a [[MAOB]] gene SNP, [[rs1799836]] was also noticed.
