Imprecise excision of the progenitor insertion, which results in a 1103bp deletion that removes exon 3a and part of the following intron. 464bp of the original insertion remain. This mutation affects specifically the short form of vari.
1103 bp deletion resulting from the imprecise excision of P{XP}varid10880 464 bp of the original insertion remain at the site. Position of deletion on reference sequence inferred by FlyBase curator.
Homozygous and variMD109/vari03953b embryos die at the end of embryogenesis with convoluted tracheal tubes. Pleated septate junctions are missing between epidermal and between tracheal cells in stage 16 homozygous embryos, while adherens junctions are well developed.
