Mutations in Snail Family Genes Enhance Craniosynostosis of Twist1 Haplo-insufficient Mice

Abstract
In Drosophila, mutations in the Twist gene interact with mutations in the Snail gene. We show that the mouse Twist1 mutation interacts with Snai1 and Snai2 mutations to enhance aberrant cranial suture fusion, demonstrating that genetic interactions between genes of the Twist and Snail families have been conserved during evolution.
