There are no available cDNA sequences for AtFH17. The prediction according to current annotation lacks some conserved sequence motifs, which can be restored by modifying the splicing pattern while taking into account the closest homologues of AtFH17 (blue arrows; source sequences, text file of the alignment here).
Comparison to the closely related AtFH13 and AtFH14 cDNA sequences allowed recovering
a better conserved AtFH17 sequence (final prediction see here).
