Mutation in sequenced strain: deletion (-5).
There is a 5 base deletion in CG14499 in iso-1, the reference sequence strain relative to RNA-seq reads from a different melanogaster strain (SRX494084). 5 bases (ACGAG) are missing between 2R:18187878 and 2R:18187879 in iso-1. This leads to a frameshift after codon 52 and early translation termination after 8 novel amino acids.
