Genetic mapping information
Comments

Breakpoint(s) molecularly mapped

(Reddy et al., 1984)

-19.3 to -18.6 kb The zero coordinate used in locating the molecular lesions in the Notch deficiencies is the first Eco R1 site in Canton-S DNA proximal to the 3C7 breakpoint of In(1)N76b8 (Kidd et al., 1983); it is 1.1 kb to the right of the zero coordinate used by Artavanis-Tsakonas et al., 1983

Comments on Cytology

Deficient for a series of bands.

(Welshons, 1974)

Left limit of break 1 from polytene analysis (FBrf0026367) Right limit of break 1 from inclusion of N (FBrf0026367) Left limit of break 2 from polytene analysis (FBrf0026367) Right limit of break 2 from polytene analysis (citation unavailable)

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
