Subject: Dredd gene correction To Whom Concerned, We would like to correct a mistake in flybase. In the 1B13 cytological region, there is a listing for a Redd gene, instead the name and symbol for this gene should read Dredd (GenBank G2199582). Also the Dredd gene is the same as the anon-1BCa (our unpublished observation) gene referenced in Voelker et al., 1989, Genetics 122: 625-642. Additionally there is a mistake in the molecular map data of that region (Steinhauer, W., and Voelker, R. personal communication). The actual physical map should read as follows: M(1)1B (1kb transcript), l(1)1Bi (3.5kb transcript), Dredd, su(s), anon-1BCb, and l(1)1Bk. Thanks in advance. Antony Rodriguez UT Southwestern Med.
