Excessive leaf-like laminae or folia in the brain of E9.5-10.5 Ptch1wig/Ptch1wig embryos resembling a wig

mortality/aging

growth/size/body
• mutant embryos are visibly larger than controls

craniofacial
• the mandibular prominence is massively overgrown
• the maxillary prominence is massively overgrown and is is about twice the size of controls
• the nasal placode is displaced and protrudes laterally
• agenesis of the fourth pharyngeal arch; a large cleft remained at the site where the third and fourth arches are normally located
• the second pharyngeal arch is severely hypoplastic
• genesis of the third pharyngeal arch; a large cleft remained at the site where the third and fourth arches are normally located

hearing/vestibular/ear
• at E10.5, the otocysts are smaller than controls

nervous system
• at E10.5, mutants display hypoplasia of the peripheral nervous system including defects in cranial ganglia branching
• at E10.5, mutants display excessive neuronal differentiation in the hindbrain
• at E10.5, mutant embryos exhibit an excess of laminae or folia within the neural plate, particularly at the level of the forebrain, midbrain and anterior hindbrain
• at E10.5, the cranial neural folds are persistently open and have an everted and enlarged appearance
• rostral crainorachischesis
• caudal to the otocyst, the cranial ganglia are hypoplastic or absent
• rudimentary condensations corresponding to the glossopharyngeal ganglion and the vagal ganglion may exist
• the facioacoustic/vestibulocochlear ganglion is abnormally shaped and persists as a round hypoplastic ganglia
• at E10.5, mutants display small facial ganglia and these are disconnected from the neural tube
• at E10.5, mutants display small glossopharyngeal ganglia and these are disconnected from the neural tube
• at E9.5, trigeminal ganglion is missing the dorsal half, or proximal root, suggesting pertubations of neural crest cell migration in mutant embryos
• at E10.5, mutants display small trigeminal ganglia and these are disconnected from the neural tube

cardiovascular system
• E9.5-10.5 wiggable embryos exhibit enhanced PECAM-1 staining compared to wild-type controls, indicative of a marked increase in endothelial cells and vasculature formation

taste/olfaction
• the nasal placode is displaced and protrudes laterally

embryo
• agenesis of the fourth pharyngeal arch; a large cleft remained at the site where the third and fourth arches are normally located
• the second pharyngeal arch is severely hypoplastic
• genesis of the third pharyngeal arch; a large cleft remained at the site where the third and fourth arches are normally located
• mutant embryos are visibly larger than controls
• at E10.5, mutant embryos exhibit an excess of laminae or folia within the neural plate, particularly at the level of the forebrain, midbrain and anterior hindbrain
• at E10.5, the cranial neural folds are persistently open and have an everted and enlarged appearance
• rostral crainorachischesis

vision/eye
• at E10.5, complete ocular agenesis is apparent, with absence of the optic vesicles; this phenotype may be secondary to the overgrowth of the maxillary prominence

respiratory system
• the nasal placode is displaced and protrudes laterally

cellular
• at E10.5, mutants display excessive neuronal differentiation in the hindbrain
