title: Cleft Palate in a Mouse Model of SOX2 Haploinsufficiency.
abstract: OBJECTIVE
  While SEX-determining region Y-Box 2 (SOX2) mutations are typically recognized as yielding ocular and central nervous system abnormalities, they have also been associated with other craniofacial defects. To elucidate the genesis of the latter, Sox2 hypomorphic (Sox2(HYP)) mice were examined, with particular attention to secondary palatal development.
  
  
  RESULTS
  Clefts of the secondary palate were found to be highly penetrant in Sox2(HYP) mice. The palatal clefting occurred in the absence of mandibular hypoplasia and resulted from delayed or failed shelf elevation.
  
  
  CONCLUSIONS
  Sox2 hypomorphism can result in clefting of the secondary palate, an effect that appears to be independent of mandibular hypoplasia and is thus expected to result from an abnormality that is inherent to the palatal shelves and/or their progenitor tissues. Further clinical attention relative to SOX2 mutations as a basis for secondary palatal clefts appears warranted.
