During data analysis, I have noticed that the sequence names of .) tin-9.2 and exos-4.1 .) eat-18 and lev-10 .) unc-17 and cha-1 are identical → gives bugs in fiddling with large datasets. ---

Dear Irene, We really wish we could “correct this!” but these are some very unusual and complicated loci which also cause us problems when handling data. There is allot of history behind the naming and annotation of these loci that we have tried many time to resolve but to no avail. All 3 of these loci have been shown to encode multiple gene products with discrete (and independent) function. The WormBase annotation not only reflects the published data but also the wishes of the worm community members that are responsible for these genes. If you would like to discuss this further, please feel free to contact Prof. Jonathan Hodgkin [genenames@wormbase.org](mailto:genenames@wormbase.org) who is responsible for overseeing gene nomenclature for the Caenorhabditis worm community. Thank you for taking the time to contact WormBase. Paul Davis [Sequence curator]
