growth/size/body

small upper incisors ( J:226455 )

• upper incisors were hypomorphic in the mutant mice

decreased body weight ( J:226455 )

• significantly less body weight than control littermates

slow postnatal weight gain ( J:226455 )

• at one week and six weeks after birth, mutant pups and mice show slower weight/length gain than controls

microcephaly ( J:226455 )

• at 4 weeks, surviving mutant mice have a smaller head

decreased body length ( J:226455 )

• at 4 weeks, surviving mutant mice have a smaller body length

disproportionate dwarf ( J:226455 )

• forelimbs and hindlimbs are disproportionally shorter compared to littermates

craniofacial

small cranium ( J:226455 )

• skull bones were smaller and less mineralized especially within the nasal and frontal bones

small upper incisors ( J:226455 )

• upper incisors were hypomorphic in the mutant mice

limbs/digits/tail
