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

integument

abnormal hair follicle morphology ( J:204142 )

• in P60 animals, hair follicle structures are retained in absence of external hair, but display abnormalities including cyst formation

abnormal hair cycle catagen phase ( J:204142 )

• cre induction at P4 causes hair follicle regression by P14 without loss of bulge stem cell markers

abnormal epidermal layer morphology ( J:204142 )

• when doxycline induction is performed from P4 to P18, epidermis exhibits increased proliferation as well as expanded expression of basal and suprabasal markers and hyperproliferation markers

• when doxycline induction is performed from P4 to P18, enlargement of intercellular spaces and some cell membrane protrusions are observed in some areas of mutant skins at P60

• defects of the interfollicular epidermis similar to those observed in conditional Ctnnb1 mutants are seen in induced mutants

abnormal keratinocyte morphology ( J:204142 )

immune system

cutaneous mastocytosis ( J:204142 )

• with doxycycline induction from P4-P18, mast cell number in the dermis is increased at P60

hematopoietic system

cutaneous mastocytosis ( J:204142 )

• with doxycycline induction from P4-P18, mast cell number in the dermis is increased at P60

mortality/aging

perinatal lethality ( J:164701 )

embryo

short rostral-caudal axis ( J:164701 )

• mutant mice exhibit a shortened anteroposterior axis

abnormal neural tube morphology ( J:164701 )

• mutant phenotype is obvious as early as E9.5 due to the presence of a shortened neural tube

nervous system

abnormal neural tube morphology ( J:164701 )

• mutant phenotype is obvious as early as E9.5 due to the presence of a shortened neural tube

absent midbrain-hindbrain boundary ( J:164701 )

• mutant mice exhibit no apparent isthmus

decreased forebrain size ( J:164701 )

• at E12.5 a severely truncated forebrain

absent choroid plexus ( J:164701 )

• at E12.5

absent midbrain ( J:164701 )

• absent midbrain

abnormal metencephalon morphology ( J:164701 )

• at E8.5, 9 of 10 embryos are in the process of being reabsorbed

embryo

embryonic growth arrest ( J:164701 )

• germline homozygotes appear arrested at E6, they do not progress past the egg cylinder stage, and by morphological criteria lack mesoderm
