All mutations/alleles(31) : Gene trapped(26) Targeted(5)
Incidental mutations (data from APF )
Male mice hemizygous for a knock-out allele show alterations in spatial learning, locomotor activation, LTP, and spike-timing-dependent plasticity. A portion of chimeras hemizygous for a gene trapped allele display forebrain deletion, posterior truncation, and failure to initiate embryo turning.
