Setting the stage for limb development
...5/6 knockout mice displayed defects in bone, inner ear
and craniofacial development. But most interestingly, the mice were also born with the claw-like limb deformities characteristic of SHFM. This work is the first demonstration that Dlx genes function in mammalian limb development, and it establishes ...
