Subject: KG00759 is an allele of both CG18078 and CG9273 KG00759 is listed in FlyBase as an allele of CG18078. The P-element insertion in KG00759 is inserted in an exon of CG9273, which is nested in an intron of CG18078. I don't know what convention you use in such cases of an insertion mutation hitting two genes. However you annotate this, the gene report for CG9273 should note that KG00759 is a mutant allele of this gene; the gene report currently states that there are no known mutant alleles. ...Bob Levis \-- \------------------------------------ Robert W.
