embryo
• about 75% of embryos at E7.5 - E9.5 display abnormalities that vary in severity

nervous system
• at E8.5 and E9.5 variable truncations of the forebrain are seen ranging from mild reduction in head size (14.3% of embryos) to partial loss of the forebrain and ill-defined brain segments (42.8%) and in severely affected embryos (14.3%) anterior truncations resembling those in Dkk1 single homozygotes

vision/eye
• poor development of the eye primordium in moderately affected embryos (42.8%)

growth/size/body
• at E8.5 - E9.5, head size is reduced by 16% compared to wild-type
