E-mail: Received 22 September 2000; accepted 8 January 2000 The enhancement of GABAergic neurotransmission has been closely linked to antipanic drug efficacy. This is the first
study to investigate a putative association of exonic sequence variants of the human GABA

receptor 1 (GABA
and susceptibility to panic disorder. Three DNA sequence variants in exons 1a1, 7 and 11 were assessed by polymerase
chain reaction-based restriction fragment length polymorphism in a case–control study among patients with panic

criteria and blood donors. There was no indication of an increased
vulnerability to panic disorder or agoraphobia with respect to the allelic variants under study. Psychiatr Genet 00:1–4
