♀	phenotype observed in females

N	normal phenotype

mortality/aging

postnatal lethality, complete penetrance ( J:145464 )

• develop to term but die in the second post natal week

nervous system

nervous system phenotype ( J:145464 )

N	• central nervous system myelination is normal up to 11 days of age (optic nerve and corpus callosum)

abnormal myelination ( J:145464 )

• severely defective myelination in the peripheral nervous system

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

nervous system

decreased myelin sheath thickness ( J:207470 )

• at P15, the myelin of peripheral axons is thinner but axons are hypermyelinated at P90

abnormal myelination ( J:207470 )

• at P15 and P90, 36.7% and 17.8% of axons with diameters >1 um are nonmyelinated, respectively compared to 3.5% and 0.8% in controls

hypermyelination ( J:207470 )

• axons are hypermyelinated at P90

• however, mice show rescue of Schwann cell development and Schwan cells are able to myelinate
