title: Gene discovery in craniofacial development and disease--cashing in your chips.
abstract: An unbiased, polygenic approach is needed to unravel the complex molecular bases of craniofacial development and disease. DNA microarrays, the current paradigm of genome-wide analysis, permit the simultaneous study of many thousands of genes, the ready identification of candidate molecules and pathways, and the compilation of gene expression profiles for whole systems--pathologic and embryonic alike. We survey the existing literature applying microarrays to craniofacial biology and highlight the value of animal models, particularly mice and chickens, to understanding molecular regulation in the craniofacial complex. We also emphasize the importance of functional studies and high-throughput assays to extracting useful data from microarray output. It is our goal to help put researchers and clinicians on the same page as microarray technology moves into the forefront of craniofacial biology.
