Study Objectives:

To investigate and elucidate the role of GABAA receptor subunits, specifically the 2 genetic markers at the GABAA α1 and GABAA 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 χ2 test demonstrated an association between the A15G variant at the GABAA α1 receptor subunit gene and zolpidem-induced CSBs (P = 0.007). The adjusted odds ratio of the GABAA 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 GABAA α1 receptor subunit gene confers a high risk of zolpidem-induced CSBs and may be considered in clinical services.
