Imprecise excision of the P{EP} element in P{EP}dntEP2158 results in a 2322 bp deletion from positions 19360852 to 19363174. This deletions uncovers most of the first exon of dnt, including the transcription start site.
A 2323bp deletion resulting from the imprecise excision of P{EP}dntEP2158 removes the first exon of dnt which included the translation start site.
In 8% of the hemisegments in dnt42.3 stage 16 embryos, lateral transverse muscles frequently bypass their normal attachment at the epidermis at muscle 12 and instead extend ventrally beyond muscle 13 and attach at a novel epidermal site located close to muscle fiber 7. The rest of the muscle pattern appears normal.
