Superoxide dismutase coding of gene polymorphisms associated with susceptibility to Parkinson's disease.

This study assessed the potential associations of gene polymorphisms in SOD1 (encoding Cu/Zn-SOD), SOD2 (encoding Mn-SOD) and SOD3 (encoding extracellular-SOD) with susceptibility to Parkinson's disease. A case-control study, including Parkinson's disease cases (n = 356) and controls (n = 370). Single nucleotide polymorphisms of SOD1 (rs2070424 A/G), SOD2 (rs4880 T/C) and SOD3 (rs1799895, C/G) were genotyped. Results indicated that AG or GG genotype carriers in SOD1 had a much greater risk of Parkinson's disease compared to corresponding AA genotypes, and allele G carriers had increased risk versus allele A carriers in the single nucleotide polymorphism (rs2070424 A/G) in SOD1. Further, TC or CC genotype carriers in SOD2 had a much higher risk of Parkinson's disease compared with corresponding TT genotypes, and the C carriers had an increased risk over allele T carriers in the single nucleotide polymorphism (rs4880 T/C) in SOD2. Together, carrying allele G in the single nucleotide polymorphism (rs2070424 A/G) in SOD1, or allele C in the single nucleotide polymorphism (rs4880 T/C) in SOD2, enhances genetic susceptibility to Parkinson's disease.
