Genomic deletion of an intron by NHEJ. Alignment of intron 1 in Dvir\GJ12838 with unaligned nucleotides from the coding sequence of Dgri\GH15541, which experienced an intron loss at this position. Direct repeats (bolded and underlined) may have been used for microhomology directed ligation during NHEJ. The second cyostine in the downstream repeat may have undergone a C→T transition.
