N normal phenotype
mortality/aging
• mutants with aberrant neural tube development do not survive birth

growth/size/body
• on rare occasions, kidneys are polycystic

vision/eye
• the eye fills with blood as development proceeds, resulting in hematoma that distorts the shape of the iris
• mutants exhibiting the eye phenotypes do not exhibit neural tube defects
• eyes beneath the closed lids are covered with a tough connective tissue layer
• observe accumulation of clear fluid and cell debris in the orbit beneath the closed eyelid after birth such that the shape of the face is distorted
• iris is folded and irregular in shape and thickness in juveniles
• adult corneas are uneven in thickness
• the corneal epithelium is often attached to the overlying lid and becomes folded and irregular in juveniles
• adult corneal epithelium differs in thickness along any diameter across the cornea and the cells are irregularly shaped and accumulate at the limbus
• corneal stroma shows disorganized keratocytes and occasional acellularity in juveniles
• adult corneas are cloudy
• adults show a partial or absent lens
• lenses appear cataractous during juvenile development
• blood-filled blisters develop over the eye starting at E11.5
• the lens is often smooth, unencapsulated with no apparent nucleus, and has no obvious anterior chamber at E16.5
• juveniles show incompletely detached lenses from the surface ectoderm which begin to degenerate and become irregularly shaped, polycystic, cataractous, vacuolated, disorganized, and often bisected by part of the iris
• at E11.5, the eye cup forms normally but the lens vesicle does not always separate completely from the head ectoderm
• adults show varied eye size from normal to small
• at E16.5, the eyelid is often not directly centered over the eyeball
• eyelids fail to close and mutants are born with open eyes
• eyelids are completely opened or only partially closed at E16.5
• adults exhibit retinal folding

cardiovascular system
• exhibit increased vascularization throughout the developing eye and head region, starting at E11.5
• the eye fills with blood as development proceeds, resulting in hematoma that distorts the shape of the iris

homeostasis/metabolism
• blood accumulates readily in the eye and exhibits decreased clotting

nervous system
• mutants without obvious eye defects show an irregularly shaped neural tube that is improperly aligned for closure at E11.5
• mutants without obvious eye defects exhibit disruption of neural tube closure in the anterior and hindbrain neuropores and are born with open neural tubes
• occasionally see clear fluid-filled blisters on the surface of the developing brain

renal/urinary system
• on rare occasions, kidneys are polycystic
• on rare occasions, a kidney is missing

embryo
• mutants without obvious eye defects show an irregularly shaped neural tube that is improperly aligned for closure at E11.5
• mutants without obvious eye defects exhibit disruption of neural tube closure in the anterior and hindbrain neuropores and are born with open neural tubes
