alleles, and
All mutations/alleles(12) : Gene trapped(1) Targeted(11)
Incidental mutations (data from Mutagenetix , APF )
Homozygous null mutants have reduced size, lessened sensitivity to touch and pain, weakness and incoordination of hind-legs, reduced corticospinal tract, impaired guidance of retinal and corticospinal axons, and in some cases, enlarged lateral ventricles. A hypomorphic line shows background effects.
