This allele carries a 652 bp deletion in the promoter region of the gene, located 2.5 kb upstream of the transcription start site. The deletion cosegregated with the aphakia phenotype. In situ hybridization studies of homozygous mutant mice did not detect transcripts in the lens placode or at later developmental stages of the lens. (J:63167, J:68175)
