Skeletal morphogenesis is affected in zebrafish larvae expressing truncated kiaa0753. (a) Heterozygous and wild-type carriers have a straight body; (b) Zebrafish expressing mutant Kiaa0753 in homozygosity present a ciliopathy-like phenotype characterized by a curved body, visible from 2 dpf; (c) Normal larvae head at 5 dpf; (d) disruption of cartilage structures were evident by 5 dpf, with mutant larvae presenting shorter head length along the anterior-posterior axis; (e,f) To quantify the phenotype, alcian blue staining was performed in wild-type and mutants, respectively; (g), and cartilage patterning was quantified according to scheme; (h) Statistical analysis showed that measurements 1–3 and 5–7 showed a significant difference between wild-type and mutant larvae (*p < 0.01) (mutant, n = 11; wild-type, n = 14).
