OBJECTIVE: To investigate the association between two estrogen receptor (ER) beta gene polymorphisms and Parkinson disease (PD) as well as Parkinson disease with dementia (PDD) in Chinese people. METHODS: Peripheral blood samples were collected from 115 PD patients (including 26 PDD cases), 56 males and 55 females, aged 64 +/- 10, and 116 sex and age-matched healthy controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to analyze the polymorphism of the fifth exon RsaI and the eighth exon AluI of ERbeta gene. Te relationship between each genotype or allele frequencies and PD/PDD was analyzed using chi-square test. RESULTS: There was no difference in the polymorphism of ERbeta genes AluI and Rsa I between the PD group and control group and between the PDD group and control group (all P > 0.05). CONCLUSION: Genetic variations from AluI and RsaI digestion in ERbeta gene do not affect the risk of PD and PDD.
