Subject: ADRC-570B Dear David, We are currently curating the abstracts for the upcoming Bellevue (Seattle) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstract: 'Retinal degeneration G (rdgG): a novel retinal degeneration mutation in Drosophila melanogaster.' You mention a gene that is new to FlyBase, rdgG. Do you have a map location for rdgG? It is nice if we can keep as many gene records as possible anchored to the map. Do you have an allele symbol for your rdgG mutant? Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC-570B Rachel, Our current data places rdgG most likely between map units 58.6-61.5 on the second chromosome. Using available deficiencies, rdgG most likely maps 45D-46A. We have designated the first allele as rdgG1. I hope that this helps. David
