Mutation in sequenced strain: frameshift (-1).
There is a one base deletion in Rx in iso-1, the reference sequence strain, relative to cDNA GB:AJ223300. One base (C) is missing between 2R:20917096 and 2R:20917097 in iso-1. This leads to a frameshift after codon 16 and early translation termination after the addition of 9 novel amino acids.
