Description

The inversion breakpoint of sasAntp73b is in intron 2 of sas. The inversion fuses the Antp promoter to the sas transcription unit, resulting in a fusion RNA consisting of exon 1 of Antp and exons 3-7 of sas.

(Schonbaum et al., 1992)

Inversion between Doc{}sasDoc (in first intron of sas) and Doc{}AntpDoc (in first intron of Antp) causes an exchange between the proximal exons of Antp and sas.

(Schneuwly et al., 1987)

Fusion of 5' exons with exons 2 upward of Antp.

      Larvae die during the first instar moult or as small second instar larvae. Abnormal tanned spots are found between the 4th and 5th rows of the setal belts in A8 in second instar hemizygous larvae.
