Imprecise excision of the progenitor P{EPg}TnksHP37069 insertion, resulting in a deletion of 1924bp which removes the first exon plus some upstream regulatory sequence of Tnks.
Approximate boundaries of 1924 bp deletion resulting from the imprecise excision of P{EPg}TnksHP37069, which removes the first exon of Tnks and some upstream regulatory sequences (estimated from Fig. 1).
