    Quantal content is approximately 50-65% higher in DysGE20705 mutants compared to wild-type. The frequency of spontaneous neurotransmitter release is elevated approximately 35-50% in DysGE20705 mutants.

    DysE6/DysGE20705 trans-heterozygotes exhibit an increase in EJP amplitude compared to controls when evoked by nerve stimulation at 0.3Hz. Quantal content is also significantly higher in DysE6/DysGE20705 trans-heterozygotes compared to wild-type.

    DysGE20705/+ heterozygotes exhibit an increase in EJP amplitude compared to controls when evoked by nerve stimulation at 0.3Hz. Quantal content is also significantly higher in DysGE20705/+ trans-heterozygotes compared to wild-type.

    Synaptic boutons in DysGE20705 appear slightly more elongated than in controls. The areas of the bouton occupied by vesicles is increase in DysGE20705 mutants compared with wild-type. The number of active zones with a T-bar relative to the total number of active zones is significantly increased in DysGE20705 mutants by approximately two-fold, whereas the overall number of active zones does not increase.
