A small deletion in the 3' untranslated region of Top1.
lethal | recessive
viable (with Top1JS)
Top1112/Top1JS is a suppressor of bang sensitive | recessive phenotype of eas2
Top1112/Top1JS is a suppressor of bang sensitive | recessive phenotype of jusiso7.8
The bang sensitive phenotype and decreased seizure threshold* of eas2 homozygotes are partially suppressed by Top1JS/Top1112. (*seizure threshold = minimum voltage of high frequency stimulation required to induce seizures).
Top1112 is rescued by Top1+t10
