Mutations,
alleles, and
phenotypes

All mutations/alleles(14) : Chemically induced (ENU)(2) Spontaneous(9) Targeted(3)
Incidental mutations (data from Mutagenetix , APF )
 

Mice homozygous for a point mutation exhibit tremor and gait abnormalities. Homozygous null mice lack the apamin sensitive component of the medium afterhyperpolarization current but have normal hippocampal morphology.
