All mutations/alleles(8) : Gene trapped(1) Targeted(7)
Incidental mutations (data from Mutagenetix , APF )
Homozygotes for a targeted null mutation exhibit severely impaired spatial learning, alterations in long-term potentiation and depression, and lack of hyperalgesia responses in a neuropathic pain model.
