[i] The exon/intron structures of gene ZNF208 and pseudogene ZNF209 are shown. Exon boundaries were determined based on cDNA comparisons of other ZNF91 family members to the genomic sequence and by GRAIL analysis. Positions of exons refer to GenBank accession no. HUAC003987 for ZNF208 and GenBank accession no. HUAC004004 for ZNF209.
