mortality/aging

postnatal lethality, incomplete penetrance ( J:88585 )

• approximately 25% died within the first 3 weeks of life

• additional mice died in the 4th week of life, but in contrast to Ebf3^tm1Reed homozygotes, the majority of mice survived to adulthood

behavior/neurological

abnormal sexual interaction ( J:88585 )

• females showed slightly reduced mating efficiency

• males exhibited a dramatically reduced mating efficiency

nervous system

abnormal olfactory bulb morphology ( J:88585 )

• olfactory glomeruli absent from dorsal olfactory bulb

small olfactory bulb ( J:88585 )

abnormal olfactory neuron innervation pattern ( J:88585 )

• olfactory neurons fail to project to the dorsal olfactory bulb
