      Homozygous embryos lack Malpighian tubules and the gut wall is 3--4 fold thicker than wild type at the junction of the posterior and anterior midgut.

      (Liu et al., 1991)

      a member of cut Lethal II group, maps proximal to ctC145 (Jack, 1985). Not suppressed by su(Hw)2 (Schalet). ctlS1/+ males, frequently show thoracic protuberances (Schalet).
