Phenotypes Associated with This Genotype

Genotype
MGI:5301974

• Allelic Composition: Lmnb2^tm1Yxz/Lmnb2^tm1Yxz
• Genetic Background: involves: 129S4/SvJae * 129S6/SvEvTac * C57BL/6

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

mortality/aging

neonatal lethality, complete penetrance ( J:178993 )

• born alive but fail to breath and die immediately after birth

respiratory system

respiratory failure ( J:178993 )

nervous system

abnormal neuronal migration ( J:178993 )

• neurons tend to stay in the ventricular or subventricular zones where they are born rather than migrating away

• neurons migrate farther than in mice null for Lmnb1

abnormal neuronal precursor proliferation ( J:178993 )

• cell plane cleavages are significantly more horizontal to the apical surface compared to control littermates

abnormal stratification in cerebral cortex ( J:178993 )

• cortical layers are disorganized
