phenotypes
All mutations/alleles(18) : Gene trapped(10) Targeted(8)
Incidental mutations (data from Mutagenetix , APF )
 
Homozygotes for a knock-out allele show no obvious brain defects but exhibit impaired T cell priming and defective Th1 responses. Homozygotes for a gene trap allele show severe retinal degeneration with reduced retinal vessels, depigmentation and dysfunction of both rod and cone photoreceptors.
