nervous system
• 26% of embryos analyzed show reduced telencephalic tissue at 12.5-14.5 dpc (days post coitum)
• severity and frequency of forebrain defects are increased in double heterozygotes, due to Hesx1 dosage decrease

vision/eye
• all embryos analyzed display severe bilateral microphthalmia or anophthalmia between 12.5 and 14.5 dpc
• some affected embryos also show reduction in telencephalic tissue
