Genomic Mutations involving Kcnq2 (1)
Incidental mutations (data from Mutagenetix , APF , CvDC )
 
Mice homozygous for a null mutation die perinatally with pulmonary atelectasis. Heterozygous mice exhibit a hypersensitivity to the epileptic inducer pentylenetetrazole. Mice homozygous for a knock-in allele exhibit spontaneous seizures and premature death.
