Increasing evidence indicates that the dysfunction of ubiquitin-proteasome system (UPS) is associated with Alzheimer's disease (AD). In the ubiquitin-proteasome pathway, Ubiquitin Carboxy-terminal Hydrolase-L1 (UCH-L1) plays an important role for the cellular clearance of abnormal proteins. Since a substitution of serine by tyrosine at codon 18, exon 3 (S18Y polymorphism) of the UCH-L1 gene exhibits a protective effect against the development of degenerative disease such as sporadic Parkinson's disease (PD) in several different ethnic groups, we hypothesized that UCH-L1 gene S18Y polymorphism may have that same effect on the pathologic process of AD. We examined UCH-L1 S18Y polymorphism genotypes of 116 sporadic AD patients and 123 healthy subjects in Chinese Han population using PCR-restriction fragment length polymorphism (RFLP) analysis. The allele and genotype data as well as data after stratification by age of onset failed to demonstrate any association between AD and S18Y polymorphism. However, after stratification by gender, female AD patients showed significantly less frequencies of Y allele and YY genotype in S18Y polymorphism than female controls (P = 0.003 and P = 0.015 respectively). We conclude that Y allele and YY genotype of S18Y in the UCH-L1 gene may have a protective effect against sporadic AD in female subjects, probably due to altering the function of UCH-L1 and the interactions among different risk factors.
