Identification of a mutation in the MP19 gene, Lim2, in the cataractous mouse mutant To3.

Abstract

The identified genetic lesion in the Lim2 gene of the cataractous mouse mutant, To3, confirms Lim2 as an ideal candidate gene. Future transgenic experiments should provide proof or disproof of a causative relationship between the identified mutation and the cataractous phenotype. These studies indicate that MP19 may play an important role in both normal lens development and cataractogenesis, and warrants more intense investigation of its role within the ocular lens.
