Notes

In chimeric embryos formed between a strain of mice homozygous for Mip^Cat-Fr and the DBA/2 strain, homozygous for the wild-type Mip allele, the lens is histologically, cellularly, and biochemically normal (J:35863). A study of the lens crystallins shows a decrease in the proportion of a-crystallins and an increase in the proportion of a-crystallins (J:6987). At birth, a-crystallin mRNAs are present in nearly normal amounts and functional capacity but are selectively lost by 40 days of age. The effect is more severe in homozygotes than in heterozygotes. The a-crystallin cellular DNA does not differ from normal (J:7668).
