- 1602 H→Q: In cu8; probable loss of dihydroorotase activity. Severe late stage embryonic lethality in 50% of animals. The few surviving mutants have a shorter and thicker pharyngeal isthmus, an abnormal knobbed tail, mild egg-laying defects, moderate fluid accumulation in the coelom and a slower growth. Actin and intermediate filaments are disorganized in the pharynx. Moderate reduction in heparan sulfate levels and increased levels of chondroitin sulfate. In an umps-1 zu456 mutant background, prevents the formation of abnormally enlarged gut granules in embryos. Complete embryonic lethality in a rnst-2 qx245 mutant background.
