Phenotypes Associated with This Genotype

Genotype
MGI:5438092

• Allelic Composition: Btbd9^{Gt(RRE078)Byg}/Btbd9^{Gt(RRE078)Byg}
• Genetic Background: involves: 129P2/OlaHsd * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

nervous system

abnormal synaptic plasticity ( J:187734 )

• paired pulse ratios at three different inter-stimulus intervals are enhanced suggesting a defect in short term plasticity

• enhanced long term potentiation suggests a defect in long term plasticity

enhanced long-term potentiation ( J:187734 )

• suggesting a defect in long term plasticity

abnormal miniature excitatory postsynaptic currents ( J:187734 )

• decreased frequency and amplitude but no changes in rise or decay times

increased paired-pulse ratio ( J:187734 )

• paired pulse ratios at three different inter-stimulus intervals are enhanced

behavior/neurological

enhanced contextual conditioning behavior ( J:187734 )

enhanced cued conditioning behavior ( J:187734 )

increased locomotor activity ( J:187433 )

• travel a greater distance in an open field assay

• increase in activity when placed in constant darkness but significant alterations in circadian rhythms

unidirectional circling ( J:187433 )

• increase in counterclockwise circling but no difference in clockwise circling

abnormal sleep pattern ( J:187433 )

• decrease in slow wave sleep and increase in awake time but no change in REM

• increase in arousals

abnormal thermosensation ( J:187433 )

• decrease in response time to a warm stimulus in a tail flick assay

• treatment with ropinirole rescues the sensory alteration

homeostasis/metabolism

increased circulating iron level ( J:187433 )

abnormal metabolism ( J:187433 )

• increase in 5-HIAA, a metabolite of serotonin, in the striatum suggesting an alteration in serotonin metabolism

• however, no alteration in serotonin levels are detected in the striatum
