Table 2. Summary of mutants mapped.

A total of 79 mutants were mapped down to 43 genes. A number of alleles were identified in genes for which no apparent null alleles existed, and these were deposited at the Bloomington Drosophila Stock Center. For a number of genes, we have found no previous reports regarding their role in CNS development (red text). 18w⁰³⁷²⁴⁷ was lethal over deficiencies for the region, but not lethal over 18w^Delta7-35. However, the 18w⁰³⁷²⁴⁷/18w^Delta7-35 allelic combination did show the expected phenotype. For Nup358 and lbe no alleles were available. However, Nup358^12A002 and lbe^12C005 were mapped to 20- and 50-kb regions, respectively, and in these intervals we did not identify any heterozygous SNPs, other than the ones in Nup358 or lbe (data not shown). For CG2469 (Ctr9), no alleles were available, but ongoing work verified that the CG2469^12P023 allele could be rescued by a UAS-CG2469 transgene (S. Bahrampour and S. Thor, unpublished observation).
