Abstract Background Tourette syndrome (TS) is a complex neuropsychiatric disorder coupled with obvious genetic heterogeneity. Studies in recent years have confirmed the association of SLITRK genes with sensory and neuropsychiatric diseases. To detect whether SLITRK6 is involved in the progress of TS, a family‐based association study was performed to explore the possible genetic association between SLITRK6 and TS in the Chinese Han population. Methods We genotyped 399 TS nuclear families trios, and then analyzed three tag SLITRK6 single nucleotide polymorphisms using the transmission disequilibrium test (TDT) haplotype relative risk (HRR) and haplotype‐based haplotype relative risk (HHRR) methods. Results The TDT showed no statistically significant allele transfer for the three polymorphisms. The HRR and HHRR also showed a negative association. Conclusions Despite the results suggesting that these polymorphisms may not be associated with susceptibility to TS in the Chinese Han population, we are still unable to determine the potential role of SLITRK6 in the pathogenesis of TS. Furthermore, the results still need to be confirmed in a larger sample size and in different populations.
