 All C. elegans WormBase genes also have a Sequence Name, which is derived from the cosmid, fosmid or YAC clone on which they reside, for instance F38H4.7, indicating it is on the cosmid ‘F38H4’, and there are at least 6 other genes on that cosmid.If a gene produces a protein that can be classified as a member of a family, the gene may also be assigned a CGC name like tag-30 indicating that this is the 30th member of the tag gene family.Assignment of gene family names is controlled by WormBase  and requests for names should be made, before publication, via the form at
