Frameshift deletion of 4:3732 through 4:3750 resulting in the addition of ICFRQYR after leucine 794 of the RB isoform and premature truncation after these novel amino acids.
Deletion of bases 4:3732..3750 in JYalpha results in a frameshift and early translation termination after the additon of 7 novel amino acids (ICFRQYR).
