Lens opacities in Aca47 mutants. Isolated lenses of wild-types (WT), heterozygotes (A/+), and homozygotes (A/A) are shown for 20 weeks of age. Lenses of the mutants are smaller than in the wildtype. Heterozygous lenses remain transparent, but it is obvious that homozygous lenses develop nuclear cataracts. Bar=0.5 mm.
