Mutations,
alleles, and
phenotypes

All mutations/alleles(36) : Gene trapped(32) Targeted(4)
Incidental mutations (data from Mutagenetix , APF )
 

Homozygotes for a targeted null mutation die at or before the morula stage. Heterozygotes show reduced growth, decreased fat accumulation, microphthalmia, and reduced female fertility.
