Deficiency complementation analysis is consistent with the lethality of the line being associated with the insertion. The insertion maps within the CG9246 transcription unit. However, since the insertion lies within a gene-rich region, the lethality can not yet be conclusively mapped to a single gene from these results. Thus l(2)k07215k07215 (representing the lethality of the chromosome) has been kept as a separate allele in FlyBase for now.
