Frameshift deletion of bases 4:201579 through 4:201583 resulting in the addition of HICAQRRYFKK after alanine 245 of all CG31998 isoforms and premature truncation after these novel amino acids.
Deletion of bases 4:201579..201583 in CG31998 results in a frameshift and early translation termination after the additon of 11 novel amino acids (HICAQRRYFKK).
