Objective: Stathmin 1 (Stmn1) is a neuronal growth-associated protein which was found to be involved in fear processing both in animals and humans. Moreover, it has been demonstrated that 2 single nucleotide polymorphisms (SNPs) of the Stmn1 gene (rs182455 and rs213641) significantly impacted individual fear and anxiety responses in German. However, there have been no reports on the correlation between Stmn1 SNPs and anxiety in Chinese. The present study thus aimed to explore such the correlation.

Methods: A sample of 567 healthy Han Chinese adults were genotyped for the Stmn1 SNP, namely rs182455, using polymerase chain reaction and restriction fragment length polymorphism analysis. Anxiety was assessed by the Chinese version of 40-item State-Trait Anxiety Inventory (STAI), which measures 2 anxiety dimensions, state and trait anxiety.

Results: The numbers of CC, CT, and TT genotypes of rs182455 polymorphism were 227 (40.0%), 263 (46.4%), and 77 (13.6%), respectively. The genotype distribution did not deviate from the Hardy–Weinberg equilibrium (χ2 = 0.004, P = .953). There were no significant differences in either state or trait anxiety among the 3 rs182455 genotype groups (F=0.457, 0.415, P=.634, .660), between the 2 dominant model groups (t=0.865, −0.195, P = .388, .845), or between the 2 recessive model groups (t = 0.106, 0.906, P = .916, .365). Moreover, no significant gender-specific differences in any STAI scores were found among the rs182455 genotype groups (all P > .05).

Conclusion: No evidence was demonstrated for the association of the Stmn1 gene polymorphism rs182455 with either trait or state anxiety in Chinese adults.
