Phenotypes Associated with This Genotype

Genotype
MGI:6392909

• Allelic Composition: Scn11a^em1Akoi/Scn11a⁺
• Genetic Background: involves: C57BL/6

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

behavior/neurological

abnormal thermal nociception ( J:268684 )

• the number of nociceptive behaviors in the cold plate test is higher than in wild-type mice, indicating cold hypersensitivity

• however, mice exhibit normal locomotor activity at 8-9 weeks and 36-38 weeks of age

decreased thermal nociceptive threshold ( J:268684 )

• mice exhibit a shorter paw withdrawal latency in the Hargreaves test indicating thermal hypersensitivity

nervous system

abnormal nervous system electrophysiology ( J:268684 )

• dorsal root ganglion neurons from 8-9 week old mice show higher input impedance

abnormal action potential ( J:268684 )

• dorsal root ganglion neurons from 8-9 week old mice show increased firing frequency of evoked action potentials but no difference in resting membrane potential
