amorphic allele - molecular evidence
Deletion of the coding region and all/part of the untranslated regions of Idgf6. Since Idgf6 resides in an intron of Pgant9, the deletion is designed to minimize the impact on non-coding regions and leave all Pgant9 exons intact.
Deletion of Idgf6 and replacement with DsRed. The deletion endpoints were determined from the reported homology arm sequences.
