Subject: ADRC: 244A and 245B Dear Anna, Christine and Siegfried, I am writing in connection with your abstracts for the upcoming Washington DC ADRC: 'brk, a component of the dpp pathway, affects patterning of the Drosophila appendages' and 'brinker, a negative regulator of the dpp pathway' You describe a gene, brk, that is new to FlyBase. Do you have a map location for brk? It is nice if we can keep as many gene records anchored to the map as possible. Thank you for your help, with best wishes, Rachel.
