behavior/neurological

tremors ( J:79382 )

• mice exhibit resting tremors beginning at 3 weeks of age

abnormal motor coordination/balance ( J:79382 )

• impaired motor function is less severe than in Pmp22^Tr-1H or Pmp22^Tr-2H heterozygotes

impaired righting response ( J:79382 )

impaired coordination ( J:79382 )

• when suspended by their tails mice exhibit repeated extension and flexion of their hindlimbs unlike wild-type mice

• in a hanging wire test mice fail to grasp with hindlimbs and fall unlike wild-type mice

decreased grip strength ( J:79382 )

abnormal gait ( J:79382 )

decreased locomotor activity ( J:79382 )

nervous system

abnormal Schwann cell morphology ( J:79382 )

• Schwann cell numbers are increased compared to in wild-type mice but not as severely as in Pmp22^Tr-1H or Pmp22^Tr-2H heterozygotes

• mice exhibit axonal atrophy

demyelination ( J:79382 )

cellular

abnormal Schwann cell morphology ( J:79382 )

• Schwann cell numbers are increased compared to in wild-type mice but not as severely as in Pmp22^Tr-1H or Pmp22^Tr-2H heterozygotes
