N	normal phenotype

nervous system

abnormal innervation pattern to muscle ( J:75311 )

• myelinated nerve fibers in the soleus and medial gastrocnemius are decreased by 12-13% compared to wild-type

abnormal somatic sensory system morphology ( J:107207 )

• the interosseous nerve is present at E16.5 but absent after birth

abnormal golgi tendon organ morphology ( J:75311 )

• golgi tendon organ numbers are decreased in the soleus (by 77%), medial gastrocnemius (by 64%), and extensor hallucis longus (by 26%)

absent golgi tendon organ ( J:75311 )

• in some cases the soleus lacks golgi tendon organs

abnormal muscle spindle morphology ( J:75311 )

• spindle density is increased in dorsal and to a lesser extent in ventral crural muscles

• at P20-22, average spindle number is increased by 57% in the soleus, by 80% in the medial gastrocnemius, and by 26% in the extensor hallucis longus

• however, spindle numbers are decreased in proximal hindlimb muscles with dorsal muscles more severely affected than ventral muscles resulting in an overall decrease in spindle density in the hindlimbs

• about 69% of spindles contain fewer than the normal 4 intrafusal fibers and these spindles also have a shorter capsule and smaller periaxial fluid space

• the missing intrafusal fibers are generally the later forming chain fibers

abnormal sensory neuron innervation pattern ( J:75311 )

• the proprioceptive branch of the soleus muscle nerve has 12% fewer myelinated fibers, innervates more spindles and fewer golgi tendon organs, and contains more group Ia afferents and fewer group Ib afferents

abnormal pacinian corpuscle morphology ( J:107207 )

• absent from the crus at E16.5 - E18.5 and P0 - P1

abnormal dorsal root ganglion morphology ( J:75311 , J:107207 )

• fewer dorsal root ganglion neurons and axonal projections express calbindin 2 (J:75311)

• about a 14% and 23% decrease in neuron numbers are seen in the L4 and L3 dorsal root ganglia, respectively (J:75311)

• a 25% and 32% decrease in myelinated nerve fiber numbers are seen in the L4 and L3 dorsal root ganglia, respectively (J:75311)

• only 0.2% of 9400 neuron profiles show calbindin 2 expression compared to 5.6% of 700 neuron profiles in wild-type mice (J:107207)

• die between 3 and 5 weeks of age

nervous system

abnormal muscle spindle morphology ( J:78232 )

• between E18 and P5 impaired muscle spindle differentiation is seen with loss of differentiated intrafusal fibers

• loss of differentiated intrafusal fibers varies between muscles with nearly complete loss in the gluteus, gracilis, biceps femoris, and semitendinosus muscles and partial loss in the pectoralis, adductor, and rectus femoris

• however, no defects in Golgi tendon organs are detected

abnormal sensory neuron innervation pattern ( J:78232 )

• fewer than 1% of the normal number of proprioceptive group 1a afferents are found in the ventral termination zone in the dorsal spinal cord; however densities in the dorsal and intermediate zones are normal

• a similar defect is seen at the forelimb and thoracic levels

• the number of PV+ axons within the muscle mass is reduced

impaired ability to fire action potentials ( J:78232 )

• after stimulation of the dorsal root ganglia monosynaptic responses are about 10 less than in wild-type and fail to evoke action potentials in motor neurons; however long-latency polysynaptic responses are similar to wild-type

• after cutaneous nerve stimulation the amplitude of monosynaptic responses is reduced between 4- and 40-fold

abnormal nerve conduction ( J:78232 )

• at P6 to P8, the latency of the fast component of compound sensory action potentials in the dorsal root ganglia is increased by 1 to 2 ms with a few axons showing even slower conduction velocities

• abnormal flexor-extensor posturing of the limbs

muscle

abnormal muscle spindle morphology ( J:78232 )

• however, no defects in Golgi tendon organs are detected
