Frameshift deletion of 4:680924 and 4:680925 resulting in the addition of TATNAPKCTK after alanine 72 of all isoforms and premature truncation after these novel amino acids.
Deletion of bases 4:680924..680925 in CG11360 results in a frameshift and early translation termination after the additon of 10 novel amino acids (TATNAPKCTK).
