Insertion of A between bases 4:1174797 and 4:1174798 and base 4:1174799 changed from G to A resulting in the addition YWCCR after glutamic acid 121 in all pho isoforms and premature truncation after these novel amino acids.
Bases 4:1174798..1174799 (GT) of pho are replaced with "ATA" leading to a frameshift and early translation termination after the additon of 5 novel amino acids (YWCCR).
