alleles, and
All mutations/alleles(3) : Gene trapped(2) Targeted(1)
Incidental mutations (data from Mutagenetix , APF )
Homozgous null mice show no overt phenotype, though mutation of this locus in conjunction with mutations in another potassium channel results in alcohol hypersensitivty, increased locomotion, and spontaneous myoclonus.
Kcnc3 interacts with 299 markers (Mir1a-1, Mir1a-2, Mir1b, ...)
