Genetic mapping information
Comments

This deletion removes multiple ribosomal protein-coding genes (in addition to other genes).

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.
    Phenotypic Data
    In combination with other aberrations

    Df(2L)VA23/Df(2L)TW203 viable. Df(2L)VA23/Df(2L)TW203 'hook' phenotype.

    NOT in combination with other aberrations

    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    The Df(2L)VA23 chromosome acts as a weak dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.

    (Mason et al., 2004)

    37D5 breakpoint is between position +16.2 and +17.0 on the Ddc map relative to the HpaI restriction site near the 3' end of Ddc.
