FIGURE 1.
A, human GDNF/GDNFOS genomic locus, gene structures, and splicing patterns. The boxes represent exons, the lines represent introns, and the triangles represent splicing patterns. B, transcripts of GDNF and GDNFOS isoforms and TaqMan probe designs. The boxes represent spliced exons, and the TaqMan probes are marked between exon junctions.
