β-CCM is a β-carboline known to have properties opposite to those of benzodiazepines. Our approach was to analyze, in mice, the genetic mechanisms involved in β-CCM-induced myoclonic seizures using recombinant congenic strains and F1 hybrids issued from these strains. Our aim was to define the extent of the multigenic character of β-CCM-induced myoclonic seizures, while also evaluating the distribution of the strength of the genes implicated in this trait. The results show that the control of reactivity to β-CCM is multigenic with notable epistatic involvement.
