phenotype observed in females
phenotype observed in males
N normal phenotype
vision/eye
• defects are observed starting at E10.5
• reduction in size of invaginating lens pit is observed in mildly and moderately affected embryos
• at E14.5, some embryos have an abnormally persistent lens stalk
• differentiation of lens is not affected in mildly or moderately affected mutant lenses
• in severely affected lenses at E10.5, no lens-like structures are present
• at E12.5, in mild cases, lens vesicle is small but relatively normal, small and abnormal in moderated cases and completely absent in severely affected embryos and neuroretinal is malformed also
• at E14.5 some embryos show disorganized lens fibers
• lens is absent in some mutants
• cataracts are present in some mice
• some mice show drastically reduced lens size
• shape of vesicle is defective
