Imprecise excision of the P{lacW}mtgS084910b insertion, resulting in a deletion of 95bp, removing 22bp of exon 1 and 73 upstream nucleotides. Part or all of the original insertion also remains.
95 bp deletion resulting from imprecise excision that removes 22 bases of exon 1 and 73 upstream bases. Position of deletion on reference sequence inferred by FlyBase curator and is approximate since the presumed start of exon 1 was not specified.
