Mutations,
alleles, and
phenotypes
All mutations/alleles(5) : Chemically induced (ENU)(1) Targeted(4)
Incidental mutations (data from Mutagenetix , APF , CvDC )
 
Mice homozygous for a null allele exhibit postnatal lethality, increased susceptibility to spontaneous and chemically-induced seizures and altered neuron electrophysiology. Mice homozygous for an ENU-induced allele exhibit abnormal gait, impaired coordination, and premature lethality.
