| Abstract: | Nonsyndromic cleft lip and palate (NSCLP), a common birth defect, affects 4,000 newborns in the US each year. Previously, we described an association between CRISPLD2 and NSCLP and showed Crispld2 expression in the murine palate. These results suggested that a perturbation in CRISPLD2 activity affects craniofacial development. Here, we describe crispld2 expression and the phenotypic consequence of its loss of function in zebrafish. crispld2 was expressed at all stages of zebrafish morphogenesis examined and localized to the rostral end by 1‐day postfertilization. Morpholino knockdown of crispld2 resulted in significant jaw and palatal abnormalities in a dose‐dependent manner. Loss of crispld2 caused aberrant patterning of neural crest cells (NCC) suggesting that crispld2 is necessary for normal NCC formation. Altogether, we show that crispld2 plays a significant role in the development of the zebrafish craniofacies and alteration of normal protein levels disturbs palate and jaw formation. These data provide support for a role of CRISPLD2 in NSCLP. genesis 50:871–881, 2012. © 2012 Wiley Periodicals, Inc. |
