Subject: ADRC-324B Dear Beth, 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: 'slipper, an X-linked locus required for dorsal closure.' You mention a gene that is new to FlyBase, slpr. Do you have a map location for slpr? It is nice if we can keep as many gene records as possible anchored to the map. Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC-324B Hello Rachel: Based on deficiency mapping, i can place slpr either, 7D13-14 or 7D21-7E1. This should become more firm in a few weeks since i am pursuing analysis of recombinant chromosomes between sn and slpr. (I am favoring the more proximal position of 7D21-7E1) Fails to complement Df(1)GE202 and Df(1)hl-a, but complements Df(1)HA11. Beth
