• thickened at E14.5
• lens tissue is reduced, opaque, and shapeless compared to in wild-type mice
• at E14.5, the lens is slightly more elongated than in wild-type mice
• at E15.5, transitional zone cells are disorganized unlike in wild-type mice
• anterior lens epithelial cells fail to exit the cell cycle at the equator unlike in wild-type mice
• anterior lens epithelial cells fail to differentiate and accumulate at the lens equator and in the posterior lens unlike in wild-type mice
• anterior lens epithelial cells fail to exit the cell cycle at the equator unlike in wild-type mice
• anterior lens epithelial cells fail to differentiate and accumulate at the lens equator and in the posterior lens unlike in wild-type mice
