Mice heterozygous or homozygous for a knock-in allele develop myotonia, increased myofiber damage, K+-sensitive paralysis and susceptibility to delayed weakness during recovery from fatigue. Homozygotes show perinatal lethality, low survival rate, unusual hind-limb clasping and reduced body weight.
