Nexus alignment of ENAM exon 9 sequences for two crocodylians, one testudine, and five birds. The stop codon in crocodylians and Chrysemys picta occurs at positions 3788–3790. A 406 bp deletion that is shared by all five birds occurs near the 3’ end of the coding region at positions 3353–3758. Additional frameshift mutations are shared by four of five birds including representatives of Anseriformes, Galliformes, and Passeriformes (2634–2637). Cry SINE elements  in Chrysemys occur at positions 994–1138 and 4782–4994. Several long strings of Ns in Chrysemys picta were abridged to shorter strings of ten Ns.
