Genotype
MGI:5295269

• Allelic Composition: Spef2^bgh/Spef2^bgh
• Genetic Background: involves: C57BL/6J * C57BL/10J

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

mortality/aging

premature death ( J:176695 )

• Background Sensitivity: average age of death is 24.5 days unlike mice on a mixed background

postnatal lethality, incomplete penetrance ( J:176695 )

• Background Sensitivity: some mice a few days after birth or within 1 week due to severe hydrocephalus unlike mice on a mixed background

reproductive system

reproductive system phenotype ( J:176695 )

N • female mice are fertile

male infertility ( J:176695 )

♂

nervous system

abnormal brain morphology ( J:176695 )
