Genetic information | Otx1 exon 1 and 2 are replaced with lacZ gene by homologous recombination. |
Phenotypic information | Homozygous mice show spontaneous epileptic behaviour and adult brain is reduced in weight by about 25%; females lack parental care. |
Breeding history | Targeted mutation was introduced in HM-1 ES cells. Mice were always maintained in a mixed C57BL/6 and DBA/2 genetic background. |
