Mutations,
alleles, and
phenotypes
All mutations/alleles(3) : Targeted(3)
Incidental mutations (data from Mutagenetix , APF )
 
Homozygous mutation of this gene results in abnormal taste sensitivity. Mice show reduced behavioral and electrophysiological responses to bitter, sweet, and unami compounds.
 
Interactions
Gnat3 interacts with 63 markers (Mir29a, Mir29b-1, Mir29b-2, ...)
