Mobilization of the progenitor insertion resulting in deletion of 5970 nucleotides (+774 to +6743 with reference to the Rnf146 transcriptional start site); 14 nucleotides from P{EPgy2}Rnf146EY09040 remain at this site.
A 5970bp deletion resulting from the imprecise excision of P{EPgy2}Rnf146EY09040 is reported to map from +774 to +6743 relative to the Rnf146 transcription start site. 14 nucleotides of insertion sequences remain at the site.
