Table 1 Differently expressed genes (P < .05) on Affymetrix GeneChip in palate tissue from patients with cleft palate only (CP) versus palate tissue from patients with cleft lip and palate (CLP), selected genes validated by QPCR. Accessions numbers are from the Affymetrix GeneChip analysis. Functions are from the functions of the human proteins listed in Gene Ontology (GO), http://www.geneontology.org/. The COGENE database was searched for expression in the relevant tissues (see Methods section) in Affymetrix chip analyses and SAGE libraries, A, absent; P, present; N.A., not available. A SAGE tag had to be identified twice or more to be considered present
