Behavior phenotype of mutant cdkl5 zebrafish (sa21938 line). (A) Spontaneous coiling and percentage of double coiling of wild-type (WT), heterozygous (cdkl5+/−) and homozygous (cdkl5−/−) embryos at 24-hpf. Data are presented as median ± interquartile range. (B) Total distance travelled by cdkl5+/− and cdkl5−/− mutant zebrafish embryos and WT embryos with 5 dpf, treated or not with PTZ. Data are presented as mean ± SD. (C) Percentage of time spent in the inner region of the well by 5 dpf WT, cdkl5+/− and cdkl5−/− embryos. Data are presented as median with interquartile range. Statistical analysis was performed using one-way ANOVA followed by Tukey’s test (B) and Kruskal–Wallis followed by Dunn multiple comparisons test (A and C). *, *** and **** indicate p < 0.05, p < 0.001 and p < 0.0001, respectively. ns indicates not significant. (D) Representative images of the locomotive trajectory of 5 dpf WT, cdkl5+/− and cdkl5−/− embryos.
