Lesion that specifically affects the p53 A isoform. Indel that results in a frameshift plus a premature stop codon after only 15 amino acid residues.
Deletion of 1bp (T) and insertion 2bp (GC) at codon 8 of p53-RA and p53-RC leads to a frameshift and early translation termination after the addition of 15 novel amino acids.
