| Genetic information | Cdkl5 exon 4 was targeted by homologous recombination. Exon 4 was flanked by two loxP sites followed by neomycin cassette flanked by FRT sites used for removal the cassette. Hprt-Cre mice were used to remove exon 4 to generate a Cdkl5 knock-out mouse. |
| Phenotypic information | Homozygous:Heterozygous knock-out mice displayed limb clasping, and motor and respiratory disturbances at approximately six weeks of age. Dendritic arborization was significantly reduced in cortical neurons from knock-out mice and evidence emerged for altered signaling in key intracellular pathways.Heterozygous:Heterozygous knock-out mice displayed limb clasping, and motor and respiratory disturbances at approximately six weeks of age.

| Breeding history | Mutant mice were crossed with C57BL/6J flp-deleter mice (Farley et al., 2000) made congenic in B6N genetic background (N10). Then mice were crossed with C57BL/6J cre-deleter mice (Tang et al., 2002) made congenic in B6N genetic background (N10). After that mice were bred for 7 generations in a C57BL/6N genetic background. The first 2 matings (flp-deleter and cre-deleter strains) were not considered in the calculation of the generations. Finally the mice were crossed with 129S2/SvHsd for 10 generations. |
