mortality/aging

embryonic lethality, incomplete penetrance ( J:169234 )

• embryos with hypermethylated differentially methylated regions die before E14.5

prenatal lethality, incomplete penetrance ( J:169234 )

• when heterozygotes are intercrossed some fraction of homozygote and heterozygote embryos die during gestation

• the number of males is reduced relative to the number of females

cellular

abnormal DNA methylation ( J:169234 )

• hypermethylation of the differentially methylated regions associated with the Peg3 and Nespas loci is detected in some null blastocysts but not in sperm

abnormal imprinting ( J:169234 )

• hypermethylation of the differentially methylated regions associated with the Peg3 and Nespas loci is detected in some null blastocysts but not in sperm

reproductive system

decreased litter size ( J:169234 )

• crosses of male or female homozygotes to wild-type mice results in smaller litters compared to wild-type to wild-type crosses

• the reduction in litter size is more dramatic when male homozygous mice are crossed to wild-type mice relative to the inverse cross

• decrease in litter size is correlated with combined parental gene dosage
