Patched1 is required in neural crest cells for the prevention of orofacial clefts.

Abstract excerpt

Defects such as cleft lip with or without cleft palate (CL/P) are among the most common craniofacial birth defects in humans. In many cases, the underlying molecular and cellular mechanisms that result in these debilitating anomalies remain largely unknown. Perturbed hedgehog (HH) signalling plays a major role in craniofacial development, and mutations in a number of pathway constituents underlie craniofacial...
