FB{}538 is inserted 5' of CG5929.

(Badal et al., 2006)

FB{}538 is cut (and therefore incomplete) on the 3' side (the right position as shown on the seqeunce).

(Badal et al., 2006)

The 5' (the left position as shown in the sequence) inverted terminal repeat of FB{}538 contains a G18T base change.
