mortality/aging
lethality throughout fetal growth and development, incomplete penetrance ( J:74666 )
• heterozygotes are detected at a reduced Mendelian frequency at late gestational stages (E14.5-E18.5), indicating some embryonic loss
postnatal lethality, incomplete penetrance ( J:74666 )
• at 2 weeks, heterozygotes are obtained at a reduced frequency of 56% vs the 67% expected for a 1:2 wild-type:heterozygote ratio
