mortality/aging
prenatal lethality, incomplete penetrance ( J:72503 )
• incomplete penetrance; more than half of double homozyous animals die before birth

embryo
decreased embryo size ( J:72503 )
• double homozygous embryos are smaller than controls

growth/size/body
decreased embryo size ( J:72503 )

postnatal growth retardation ( J:72503 )

reproductive system
arrest of male meiosis ( J:72503 )

arrest of male meiosis ( J:72503 )
• spermatogenesis in impaired with an arrest of differentiation at the transition stage between early and late spermatocytes; an accumulation of preleptotene spermatocytes and the appearance of apoptotic mid to late pachytene spermatocytes with meiotic defects were noted
