Amino acid replacement: A246E.
The vast majority of PsnA246E.PEPC.L flies exhibit neurogenic defects, ranging from mild to severe, manifesting as a rough eye phenotype, wing notching, and abnormal thoracic bristle patterning. A number of these flies die at the late prepupal or pupal stage.
Based on statistical analysis of the age of onset and the severity of the phenotype, the following Psn alleles can be ranked in the following order, from strongest to weakest: PsnL166P.PEPC.L = PsnL173W.PEPC.L = PsnP436Q.PEPC.L = PsnV272A.PEPC.L = PsnL235P.PEPC.L > PsnM146L.PEPC.L = PsnM139V.PEPC.L = PsnH163R.PEPC.L = PsnE280A.PEPC.L = PsnA246E.PEPC.L = PsnG206A.PEPC.L > PsnA79V.PEPC.L = PsnF175S.PEPC.L = PsnE318G.PEPC.L.
