Imprecise excision of the progenitor insertion, generating a 992 bp deletion encompassing the transcriptional and translational start sites of HEATR2.
A 992 deletion resulting from the imprecise excision of P{EPgy2}NK7.1EY06677 that includes the HEATR2 5' UTR and 390 bp of coding sequence.
Homozygous larvae are smaller than controls with no obvious morphological defects.
