Genomic structures for Retinoic Acid Receptor Alpha and BARX2 and their mutational analyses as candidate genes for craniofacial disorders.
We present here the genomic structures for two genes implicated in craniofacial development. Retinoic acid receptor alpha (RARA), or a gene in its vicinity, has been implicated in non-syndromic cleft lip and palate, based on both association and linkage studies. Using primers directed to the 3' -UTR of the published cDNA sequence, we screened a human genomic BAC library to obtain a clone containin
