phenotype observed in males
N normal phenotype
cellular
• MEFs exhibit an increase in nuclear volume, but a more compact morphology as measured by shape factor
• mitotic cells from MEFs have a significant increase in chromosomal bridges, rearrangements, fragmented ends, multiple tri-radial chromosomes, and endoreduplication
• MEFs exhibit decreased genomic integrity (normal spread 47.8%) in contrast to wild-type (normal spread 65.7%)
• MEFs exhibit an increase in the number of pericentric heterochromatin foci as determined by DAPI staining
• cell cycle analysis on MEFs indicates an increase in time spent in G2/M phase, decreased time in G0/G1 phase and no change in time spent in S phase

embryo
• E12.5 embryos are visibly abnormal and exhibit reduced growth, however, at this time point Mendelian ratios from a heterozygote x heterozygote mating are as expected

growth/size/body
• E12.5 embryos are visibly abnormal and exhibit reduced growth, however, at this time point Mendelian ratios from a heterozygote x heterozygote mating are as expected

mortality/aging
• numbers of homozygotes produced from a heterozygote x heterozygote mating are significantly less than expected
