craniofacial
• mice exhibit one incisor and three molars in each quarter of the jaw unlike in wild-type mice
• some mice are missing the incisors
• molars exhibit a reduced number of cusps compared to in wild-type mice
• some mice exhibit a loss of the third molar

skeleton
• mice exhibit one incisor and three molars in each quarter of the jaw unlike in wild-type mice
• some mice are missing the incisors
• molars exhibit a reduced number of cusps compared to in wild-type mice
• some mice exhibit a loss of the third molar

endocrine/exocrine glands
• mice produce no sweat and lack sweat glands as in EdaTa homozygotes
• mice produce no sweat

integument
• mice produce no sweat and lack sweat glands as in EdaTa homozygotes
• mice produce no sweat
• mice possess only awl hairs
• mice exhibit a bald patch at the top of the vertex that is expanded in some mice into the neck and extends laterally in a symmetrical pattern
• alopecia is evident at the time of first hair emergence and not associated with sex, age or hair cycling
• compared to in EdaTa homozygotes
• mice lack primary and secondary hair follicles
• however, treatment with Eda-A1 restores secondary hair follicles
• at E18, follicle development in the center of the cranium is absent

growth/size/body
