Genetic mapping information

Proximal breakpoint about 80 kilobases to the left of the proximal breakpoint of In(3R)Hu on the DNA map of Garber et al., 1983 and 178-182 kilobases to the right of the proximal breakpoint of Tp(3;3)Dfdrv3 on the DNA map of Scott et al., 1983 ('+' values to left in walk of Garber et al. and to right in walk of Scott et al.). Distal breakpoint at about +56 kb on the molecular map of Cavener et al., 1986. Antp transcripts found in head, some of them being fusion RNAs between Antp and sas, a gene normally expressed in the head (Frischer, Hagen and Garber, 1986, Cell 47: 1017-23).

Comments on Cytology

An insertion of 3 bands, origin and content of these bands is unknown, into 84D.

Left limit of break 1 from polytene analysis (FBrf0039287) Right limit of break 1 from complementation mapping against Antp (FBrf0034841) Limits of break 2 from polytene analysis (FBrf0039462)
