[Association of two polymorphisms in ubiquitin carboxy-terminal hydrolase-L1 gene with Parkinson's disease in Shanghai].
OBJECTIVE
To explore the relationship of polymorphisms in the ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1) gene with Parkinson's disease(PD)in Shanghai Han Nationality.


METHODS
The distribution of a Serine18Tyrosine polymorphism in exon 3(C/A) and a Serine89Phenylalanine polymorphism in exon 4(C/T)of UCH-L1 gene were detected in 164 PD cases and 172 healthy controls, using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) method.


RESULTS
(1)The C allelic frequency in exon 3 of UCH-L1 gene in PD patients(62.2%) was significantly higher than that of the healthy controls(51.7%) (OR=1.53, P=0.006), as was the C/C genotype(OR=1.90, P=0.008). (2)There was no significant difference in the distribution of the C/T allele and genotypes in exon 4 between PD patients and healthy controls.


CONCLUSIONS
The C allele in exon 3 of UCH-L1 gene might be one of the risk factors for PD in Shanghai Han Nationality, but the polymorphisms of C/T in exon 4 showed no association with the onset of PD.
