Paraoxonase 1 (PON1) is involved in the metabolism and detoxification of insecticides and pesticides. Two polymorphisms within the gene affect the enzyme activity. One is a methionine to leucine change at position 54 (M54L) and the other is a glutamine to arginine variant at position 192 (Q192R). There are contrasting reports assessing the role of these variants in Parkinson's disease (PD). We performed a case--control association study in order to elucidate the possible contribution of variability within PON1 to the risk of sporadic PD in a Finnish population. There was no statistically significant association of the allele, genotype or haplotype distribution with PD (all P values > 0.75). Our results suggest that the M54L and Q192R polymorphisms are not major risk factors for PD in the Finnish population.
对氧磷酶1(PON1)参与杀虫剂和农药的代谢与解毒过程。该基因内的两种多态性会影响酶的活性。一种是第54位的甲硫氨酸变为亮氨酸(M54L),另一种是第192位的谷氨酰胺变为精氨酸(Q192R)。关于这些变体在帕金森病(PD)中的作用,有相互矛盾的报道。我们进行了一项病例对照关联研究,以阐明PON1基因变异对芬兰人群散发性PD风险的可能影响。等位基因、基因型或单倍型分布与PD之间无统计学显著关联(所有P值>0.75)。我们的结果表明,M54L和Q192R多态性不是芬兰人群PD的主要风险因素。
