Exc.

Formation of large round cysts in the excretory canal. The cysts begin to form shortly before hatching and is penetrant. The cysts grow in size throughout larval and adult stages, and can be lethal. The cysts form primarily at the canal tips. Some of the larger cysts may be visible by low power microscopy. Slight variable defects in the tail whip. Impenetrant distal tip cell migration defects (Mig).

Wide, meandering excretory canals, with some septate fluid-filled cysts. Canal enlargement visible from L1 through adult. Defect visible only by Nomarski microscopy. n2669 was originally listed as an allele of exc-5. Later repeated complementation tests showed n2669 to be an allele of a novel locus positioned close to exc-5.
