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

limbs/digits/tail

abnormal interdigital cell death ( J:78767 )

• cell death in the necrotic zones is suppressed in forelimbs and hindlimbs at E13.5 and E14.5

abnormal apical ectodermal ridge morphology ( J:78767 )

• expression analysis suggests a delay in the regression of the AER at E12.5

brachydactyly ( J:78767 )

• on P2 mice show proportionally shortened digits

camptodactyly ( J:78767 )

• increased flexion of the digits of both the forelimb and the hindlimb

postaxial polydactyly ( J:78767 )

• a postaxial extradigit is seen in both the forelimb and the hindlimb

preaxial polydactyly ( J:78767 )

• an extra preaxial digit rudiment is sometimes seen in the hindlimb

syndactyly ( J:78767 )

• the syndactyly of adult forelimb is so pronounced that the digits can not be separated

• in newborns on the forelimbs and the hindlimbs the digits are incompletely separated

polysyndactyly ( J:78767 )

interdigital webbing ( J:78767 )

• seen at E14.5 and in adults

growth/size/body

slow postnatal weight gain ( J:78767 )

• equal in weight at birth but decreased weight gain over time

embryo

abnormal apical ectodermal ridge morphology ( J:78767 )

• expression analysis suggests a delay in the regression of the AER at E12.5

• various abnormalities in vibrissae

cellular

abnormal interdigital cell death ( J:78767 )

• cell death in the necrotic zones is suppressed in forelimbs and hindlimbs at E13.5 and E14.5
