mortality/aging
• 7 of 37 homozygotes die by P20 compared to only 1 of 69 or 2 of 35 for heterozygous and wild-type mice, respectively
|
growth/size/body
• similar weight to wild-type at birth but decreased by P6
• on average mice weigh 40% and 20% less than wild-type at P20 and P56, respectively
• a few severely affected mice weigh 50 - 60% less than wild-type and generally die before weaning
