Deletion within the complex inaF locus. The deletion removes the first exon of inaF-D, and also deletes part of the 3' exon that is common to inaF-A, inaF-B, inaF-C and inaF-D.
Approximate boundaries of a ~3.7kb deletion that extends downstream from P{walter}inaFP105p about halfway through the common exon for inaF-A, inaF-B, inaF-C, and inaF-D and removing the coding sequence for inaF-D.
