Prdm16 is required for normal palatogenesis in mice

Hum Mol Genet. 2010 Mar 1;19(5):774-89. doi: 10.1093/hmg/ddp543. Epub 2009 Dec 11.


Transcriptional cofactors are essential to the regulation of transforming growth factor beta (TGFbeta) superfamily signaling and play critical and widespread roles during embryonic development, including craniofacial development. We describe the cleft secondary palate 1 (csp1) N-ethyl-N-nitrosourea-induced mouse model of non-syndromic cleft palate (NSCP) that is caused by an intronic Prdm16 splicing mutation. Prdm16 encodes a transcriptional cofactor that regulates TGFbeta signaling, and its expression pattern is consistent with a role in palate and craniofacial development. The cleft palate (CP) appears to be the result of micrognathia and failed palate shelf elevation due to physical obstruction by the tongue, resembling human Pierre Robin sequence (PRS)-like cleft secondary palate. PRDM16 should be considered a candidate for mutation in human clefting disorders, especially NSCP and PRS-like CP.
