craniofacial
• at E13.5, mutant mice fail to form a distinct single layer of dental epithelium unlike heterozygous controls
• at E14.5, mutant mice do not form an enamel knot structure and the size of the tooth germ is reduced compared to controls; the number of proliferating cells in the outer and inner epithelia and surrounding mesenchyme is reduced by 50% in mutant mice
• at E17.5, the inner dental epithelium is not polarized, forms an elongated shape and remains rounded in shape, in contrast to morphology in controls
