Previous localization of breakpoint refined to approximately 8.5--9.0kb upstream of h.
Deletion of upstream regulatory sequences of h, leaving approximately 10kb of upstream sequences intact.
Rearrangement of chromosome upstream of the h promoter. Approximately 5.5-9.5kb of upstream sequences remain intact.
Cuticle defects.
Regulatory mutation causing alterations in hairy expression in cellular blastoderm that result in a partial version of the wild-type pattern (Howard, Ingham and Rushlow, 1988).
