Single-base, frameshift deletion of 4:560777 (R6) resulting in the addition of VTIYPHLAITTLL after phenylalanine 93 of the Pur-α RA, RB, RC, RE and RF protein isoforms and premature protein truncation after these novel amino acids.
Single base deletion at T:560777 in codon F93 of most Pur-alpha isoforms results in a frameshift and early translation termination after the addition of 13 novel amino acids (VTIYPHLAITTLL).
