• Allelic Composition: Dnmt3b^tm6Enl/Dnmt3b^tm7Enl
• Genetic Background: involves: 129S4/SvJae * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

neonatal lethality, incomplete penetrance ( J:106540 )

• normal numbers of pups are born but most die within 24 hours

postnatal lethality, complete penetrance ( J:106540 )

• almost no (only 1) homozygous mice survive to weaning

growth/size/body

abnormal nasal bone morphology ( J:106540 )

• skeletons of newborn mutants show similar defect to that seen in adult Dnmt3b^tm7Enl mutants

decreased birth weight ( J:106540 )

• at birth, mutants are less than 2/3 the weight of normal littermates
