the original Mouse strains that were made were deficient in either of two of essential etapa G genes one called a to g5 and another one called a to g7 and these mice were developed in Japan and these mice are born but they fail to survive the neonatal starvation period so when mammals are born meaning once they are cut off from an umbilical nutrient source it's almost like they have a glycogen storage disease you know those conditions where you can't produce any glycogen but it's uniformly fatal if not treated the moment you're cut off from an umbilical source of nutrient right so that neonatal starvation period between the cut off of the placenta and suckling is a common feature in mammals and there's potent induction of etapa G during that period I can't speak for humans but certainly I would think so and in mice that's exactly what happens and so these are top of G deficient newborn mice don't survive
