Engineered Y145C substitution mutation in endogenously GFP-tagged ahcy-1 locus. ahcy-1(Y145C) mutation mimics the pathogenic human mutation AHCY Y143C. ahcy-1(Y145C) mutants have a prolonged lifespan and are larger than control animals. ahcy-1(Y145C) mutants are fertile and produce a brood of laid and hatched eggs similar to control animals. ahcy-1(Y145C) mutants show a slight increase in SAH and a decrease in SAM levels, leading to an increased SAH to SAM ratio.

spr28 is a 239-nucleotide deletion (bp 45-285) and insertion of a jump board gRNA sequence (Duan et al. 2020) within the 3' UTR of the endogenously-tagged pos-1 locus. GFP::POS-1 protein expression is mis-regulated causing overexpression throughout the gonad where it is not normally expressed. A large portion of progeny fail to properly develop a germline. Other phenotypes include reduced brood size, reduced hatch rate, hermaphrodites developing only one gonad arm, oogenesis defects, and multi-vulva. Temperature stress of 25C increases severity of phenotypes. Generated in DG4222 background that was 3x outcrossed. Reference: Varderesian HV, et al. PLoS Genet. 2026 Apr 27;22(4):e1012129. doi: 10.1371/journal.pgen.1012129. PMID: 42044121.
