Study objectives: To investigate and elucidate the role of GABA(A) receptor subunits, specifically the 2 genetic markers at the GABA(A) α1 and GABA(A) α6 receptors, in zolpidem-induced complex sleep behaviors (CSBs).
Design: Genetic association study.
Setting: Kaohsiung Medical University-affiliated hospitals, Kaohsiung, Taiwan.
Patients: 30 zolpidem-induced CSB subjects and 37 controls.
Interventions: N/A.
Measurements and results: The χ(2) test demonstrated an association between the A15G variant at the GABA(A) α1 receptor subunit gene and zolpidem-induced CSBs (P = 0.007). The adjusted odds ratio of the GABA(A) α1 receptor subunit genotype for the risk of zolpidem-induced CSBs was approximately 10 (OR = 9.99, 95% CI = 1.82, 74.87; P = 0.013).
Conclusions: The finding reveals that the A15G variant at the GABA(A) α1 receptor subunit gene confers a high risk of zolpidem-induced CSBs and may be considered in clinical services.
