The following information accompanied stocks donated to the Bloomington Drosophila Stock Center by Amin Ghabrial, University of Pennsylvania School of Medicine. The following alleles, originally published as "impatent" alleles in Ghabrial et al, 2011 (FBrf0214368), have now been mapped and identified as alleles of Sac1 (FBgn0035195). Sac11472 (originally impatent1472) is TGG to TGA Opal, resulting in W207Stop. Sac11757 (originally impatent1757) is CAG to TAG Amber, resulting in Q216Stop.
