Abstract excerpt
Two regulatory signals play major roles in digit patterning during vertebrate limb development, the SHH morphogen and the BMP antagonist Gremlin1. Their dynamic expression in limb buds is controlled by distant cis-regulatory elements embedded in unrelated neighboring genes, which has confused identification of the primary cause of different types of congenital limb malformations affecting mice and humans....
