Expression of the Rieger syndrome Pitx2 protein in mouse development
The Rieger syndrome, an autosomal dominant disorder involving ocular, dental, and umbilical defects is caused bymutations in PITX2, a Bicoid type homeobox protein. Moreover, Pitx2 is involved in the Nodal/Sonic hedgehogpathway that determines left/right polarity. Mouse Pitx2 mRNA is expressed in eye, tooth and umbilicus consistent withthe human Riegers phenotype. It is also asymmetrically expresse
