Abstract

The SWXL-4 recombinant inbred mouse strain is unusually sensitive to recurrent tonic-clonic seizures upon routine handling and to seizures induced by chemoconvulsants. In a conventional intercross with the ABP/Le strain, we previously mapped a SWXL-4-derived quantitative trait locus called Szf1 (seizure frequency 1) to Chromosome 7. In the present study, we confirm the existence of Szf1 in both an independent cross and a congenic strain. However, derivative congenic recombinant strains show that an interaction between at least two genes on Chromosome 7-each of which has a very small effect on its own-account for Szf1.
