Mutations,
alleles, and
phenotypes
All mutations/alleles(3) : Targeted(3)
Incidental mutations (data from Mutagenetix , APF )
 
Homozygous mice display a decreased lifespan, cachexia, increased blood urea nitrogen, proteinuria, kidney inflammation, and a hyperdistended and neurogenic urinary bladder. Mice homozygous for a second null mutation display reduced chemical pain persistence responses but are otherwise healthy.
