Abstract
The purpose of this study was to investigate the association between MCP-1 –2518G/A
polymorphism and Tourette syndrome (TS) in Chinese Han population. We collected 324
Chinese Han individuals from 108 TS nuclear families from Chinese Han population and
employed polymerase chain reaction and restriction enzyme digestion for determining
the genotype of MCP-1 –2518G/A polymorphism. The data were analyzed using the transmission
disequilibrium test, the genotype haplotype relative risk and haplotype-based haplotype
relative risk. No biases were observed in the transmission of either of the two alleles
(χ2 = 0.016, df=1, P = 0.898) to the affected probands in the total sample. The analyses of transmission
disequilibrium test, haplotype relative risk and haplotype-based haplotype relative
risk did not indicate any associations at MCP-1 –2518G/A with TS. Our results suggest
that MCP-1 –2518G/A is not associated with susceptibility of Tourette syndrome in
Chinese Han population.
