NJ555 C. elegans exc-3(rh207) X. Show Description
Excretory canal defect. Canals are shortened and animal is somewhat pale. Defect visible only by Nomarski microscopy. Tail spike is often malformed.
NJ831 C. elegans exc-3(rh186) X. Show Description
Excretory canal defect. Hypomorphic allele. Canals are slightly shortened. Defect visible only by Nomarski microscopy.
NJ51 C. elegans exc-1(rh26) X. Show Description
Excretory canal defect. Large fluid-filled cysts appear randomly along the excretory canal, especially at the tips: 100% penetrant. Cysts often visible as clear spots by low-power microscopy. Shortened canals. Smaller cysts in amphid sheath. Stop mutation in 2nd Ras-like IRGP domain. Encodes homologue of human IRGC. [NOTE (08/2025): The correct genotype of this strain is exc-1(rh26), not exc-3(rh26) as previously described.]
NJ682 C. elegans exc-3(rh251) X. Show Description
Cystic canal.
